Title
Security advisory: Pre-authentication RCE in Ontotext GraphDB 11.4.3 Free edition (Ontotext / Graphwise)
Summary
0day Rubbish Research Team is publicly disclosing a vulnerability in Ontotext GraphDB 11.4.3 Free edition (Ontotext / Graphwise). The research is published and a proof-of-concept is available. Pre-authentication RCE (CVSS 9.8, pre-authentication) Ontotext GraphDB 11.4.3 Free edition defaults to security=false, which bypasses the entire Spring Security filter chain. As a result, /rest/repositories/ruleset/upload and /repositories/* are anonymously reachable. A .pie ruleset upload is compiled at runtime by the system javac and loaded into the server process. RuleCompilerBase.compilePrefices inlines the namespace prefix verbatim into the generated Java source with only .trim() and no validation. An attacker injects Java code in the prefix; creating a graphdb:Sail repository triggers infer.initialize(), which executes the injected Runtime.exec as the GraphDB process user (root). No authentication and no license are required. Dynamically verified with uid=0(root). Impact: Full host compromise as root (the GraphDB process user); the attacker can read any file, execute arbitrary commands, and take full control of the GraphDB host and its repositories.

Title
Security advisory: Pre-authentication RCE in DataStax Enterprise (DSE) 6.8.49 (DataStax)
Summary
0day Rubbish Research Team is publicly disclosing a vulnerability in DataStax Enterprise (DSE) 6.8.49 (DataStax). The research is published and a proof-of-concept is available. Pre-authentication RCE (CVSS 9.8, pre-authentication) DataStax Enterprise (DSE) 6.8.49 runs a Gremlin Server on WebSocket 8182. The default configuration has the gremlin_server authentication section commented out, which means TinkerPop's default allowAll authenticator - no authentication. The gremlin-groovy sandbox is enabled by default, but the sandbox only wraps the top-level submitted script; groovy.lang.Script.evaluate(String) creates a fresh GroovyShell with a default CompilerConfiguration that does not include the SandboxTransformer, so a nested string is compiled and executed sandbox-free. An attacker submits this.evaluate("<nested script>"); the nested script runs ["/bin/sh","-c","<cmd>"].execute().text, executing arbitrary system commands as the dse user. Dynamically verified. Impact: Full read of the host filesystem and configuration as the dse user, arbitrary OS command execution, and full control of the DSE host and database services.

Title
OpenZFS Linux open zpool manipulation and escapes via unprivileged userns
Summary
I am hopeful that upstream patches and remediation guidance will be available soon. I have been sitting on these for a bit, and have run this through AI services hosted in Singapore and the United States, and had notified CERT on 8/12/2026. In order to minimize the risk of asymmetric knowledge of these threats being used against defenders, I am opting for full-disclosure. Cheers from HOPE --Bird ## Report metadata - **Product:** OpenZFS on Linux (`spl.ko` and `zfs.ko`; out-of-tree and not part of the Linux kernel source tree) - **OpenZFS revision audited:** `9b7642df931a765509403318553f2910daf71305` (development version `2.4.99-1`, commit title "Harden recv record validation") - **Linux validation kernel:** `7.2.0-rc3-00275-gaf5e34a41cd6` - **Validation environments:** disposable QEMU guest with generic KASAN and `CONFIG_KASAN_VMALLOC=y`; a stock IncusOS appliance guest for deployment-level authorization/volume-swap validation; disposable QEMU appliance VMs for Proxmox VE, TrueNAS SCALE, and Unraid dynamic reachability testing. Release-mode OpenZFS modules unless stated otherwise. - **Research dates:** 2026-07-17 through 2026-07-25 - **Report updated:** 2026-07-25 - **Reporter:** Erica Windisch - **Tracker umbrella:** [issue #26]( https://github.com/ewindisch/linux-research-tracker/issues/26) All kernel execution used disposable QEMU/cloud-hypervisor guests — the KASAN research guest or the stock IncusOS appliance guest. Host-side work was limited to building, offline image construction, and driving those guests. ### Revision notes - **2026-07-25 (validation-chain results):** OZ-3c and OZ-6 move from **LIKELY** to **VALIDATED** with dynamic triggers in the KASAN guest (OZ-3c: UBSAN array-index-out-of-bounds at `zfs_replay.c:115`; OZ-6: KASAN null-ptr-deref in `vdev_is_concrete` and slab-out-of-bounds in `spa_ld_log_sm_cb`). QNAP QZFS static analysis validates Z1/Z2/dnode-bonus S3 and gang overrun, and BLOCKS log-spacemap S4 (feature absent). The upstream patch audit confirms every OZ finding remains **UNFIXED** at upstream master HEAD `3020c18c` (2026-07-24); only OZ-7 has an open, contested PR (#18620). Full audit: [`research/upstream-patch-audit.md`](../research/upstream-patch-audit.md). - **2026-07-25 (OZ-4 on Proxmox VE):** the Proxmox VE 8.x OZ-4 cell is upgraded from provisional to a confirmed dynamic verdict. On `6.8.12-37-pve` / OpenZFS `2.2.10-pve1`, importing the armed dnode-bonus pool (`dn_bonuslen= 0x400`, `zfs-77-d77-s3v2.img`) **from inside the delegated LXC container** (CT100 with the OZ-1 verified `/dev/zfs` passthrough) fired the `dbuf_read_bonus` overflow on `spa_tryimport → spa_load → spa_ld_trusted_config` and crashed the kernel (NULL-deref in `strcmp` during `vdev_open_children_impl`; host-side corroboration showed SLUB `LIST_POISON` heap corruption in `dbuf_sync_list`). OZ-4 is therefore **VIABLE from the delegated/privileged container** and **BLOCKED by default** (default unprivileged LXC has no `/dev/zfs`). A container→root shell was not reproduced on the stock appliance (release kernel faults deterministically; no KASLR leak). Full verdict and evidence: `linux-research/.fleet-coord/oz4-proxmox-verdict.md`; `linux-research/appliance-harness/proxmox-ve/runs/20260725T150254Z/evidence/`. - **2026-07-25 (OZ-4 on Unraid):** the Unraid 7.3.0 OZ-4 cell is upgraded from provisional to a confirmed dynamic verdict. On `6.18.29-Unraid` / OpenZFS `2.4.1-1`, importing the inflated-bonus pool (`dn_bonuslen=0x1000`, `zfs-77-d77-s3v3.img`) from a `--privileged` Docker container fails `insufficient replicas` while the structurally identical clean control imports ONLINE; the kernel survives (silent heap corruption, no panic/Oops). OZ-4 is therefore **VIABLE from `--privileged`** and **BLOCKED** by default and `--device /dev/zfs` (no `/dev/zfs` / no `CAP_SYS_ADMIN`). A container→root shell was not pursued (requires heap grooming + KASLR bypass). Full verdict and evidence: `linux-research/.fleet-coord/oz4-unraid-verdict.md`; `linux-research/appliance-harness/unraid/runs/20260725T150925Z/evidence/`. - **2026-07-25 (OZ-4 OCI delivery on IncusOS):** an OCI image (`oz4-delivery:latest`) carrying the armed pool (`d77.img`) was built with podman, repacked as an Incus image, and launched as a default unprivileged Incus container on IncusOS `202607192224` (OpenZFS `2.4.3-1`). The container received `/dev/zfs` and the ioctls were authorized (OZ-1 reachability **VIABLE**), but the host kernel could not open the file vdev at the container-relative path (`/opt/d77.img`), so the OZ-4 overflow never fired (**BLOCKED** for the in-container E2E fire). IncusOS's shell-less design removes the host-side bind-mount escape hatch that made the fire possible on Proxmox VE. Full verdict and evidence: `linux-research/.fleet-coord/oz4-oci-incusos-verdict.md`; `linux-research/incusos-spike/runs/20260725-oz4-oci/evidence/`. - **2026-07-25 (OZ-4 OCI delivery on TrueNAS SCALE):** the same OCI image (`oz4-delivery:latest`) was launched as a default unprivileged Incus container on TrueNAS SCALE 25.04.2.4. The entrypoint auto-fired the import ioctl, but the host kernel could not open the container-relative file vdev (`/opt/d77.img`), so the OZ-4 overflow never fired (**BLOCKED**). This refines the prior TrueNAS host-side **VIABLE** verdict: the overflow is reachable from a host path, but not from a self-contained OCI image in a default container. Full verdict and evidence: `linux-research/.fleet-coord/oz4-oci-truenas-verdict.md`; `linux-research/appliance-harness/truenas-scale/runs/20260725T190000Z/evidence/`. - **2026-07-25 (OZ-4 on TrueNAS):** the Dynamically tested appliances table gains an **OZ-4 column**. TrueNAS SCALE 25.04.2.4 (running OpenZFS `2.3.0-1`) is **VIABLE** for OZ-4 from the default unprivileged container: the armed dnode-bonus pool imported ONLINE with no error erevent (oversized `dn_bonuslen` accepted, not rejected) on the production non-KASAN kernel, and the same image fired `Write of size 1024 in dbuf_read_impl` via `spa_tryimport` under KASAN. The kernel survives the corruption; a container→root shell is not demonstrated (neighbor-lottery + KASLR, as in the 77b campaign). Proxmox VE and Unraid OZ-4 cells are marked **BLOCKED** by default pending their sibling fleet validation tasks. Full verdict and evidence path: `linux-research/.fleet-coord/oz4-truenas-verdict.md`. - **2026-07-25 (OZ-4 OCI delivery, round 2 — VALIDATED on TrueNAS SCALE and Unraid):** the malicious-OCI-image vector is upgraded from **BLOCKED** to **VALIDATED** on two appliances. The round-1 blocker was that the host kernel's `vdev_file_open` resolves vdev paths in the host mount namespace, so a container-internal `/opt/d77.img` is never opened. Round 2 defeats this with an **identical-path host bind mount** (the image entrypoint stages its embedded armed pool onto a bind-mounted host path visible at the same absolute path in both namespaces, then imports from that path). On **TrueNAS SCALE 25.04.2.4** the vector fires from a **default unprivileged** Incus container (no `security.privileged`, no explicit device add — only the default `/dev/zfs`, an identical-path `disk` bind, and a `1777` host staging path): the armed import **panicked the production kernel** (GPF in `__kmalloc` on the `spa_tryimport → spa_config_generate` path, crashing task `Comm: zpool` as the container's mapped uid in `ZFS_IOC_POOL_TRYIMPORT`), while the structurally identical clean control imported ONLINE. On **Unraid 7.3.0** the image-carried payload fires via `docker run --privileged` (the required and sufficient capability); the negative control showed the bind mount is not even required under Unraid's `vfs` storage driver. The Unraid result is **expected behavior** — a `--privileged` container holds full host capabilities by design — and is retained for matrix completeness only; it is not scored as a finding. The TrueNAS round-2 fire is the significant result, but note its two deployment concessions: an identical-path host bind and a world-writable host staging path must be granted to the container (as an app manifest's hostPath grant would provide). The Unraid kernel survives (silent corruption → `insufficient replicas`); the TrueNAS crash is a **reliable image-delivered container→host-kernel DoS** — no heap grooming required. IncusOS remains **BLOCKED** for this vector (shell-less appliance; no host bind-mount escape hatch). Full verdicts and evidence: `linux-research/.fleet-coord/oz4-oci-truenas2-verdict.md`, `linux-research/.fleet-coord/oz4-oci-unraid-verdict.md`; `linux-research/appliance-harness/truenas-scale/runs/20260725T193000Z/evidence/`, `linux-research/appliance-harness/unraid/runs/20260725T194343Z/evidence/`. - **2026-07-26 (OZ-4 OCI on IncusOS, round 2 — VALIDATED with ZERO host-side setup):** IncusOS flips from the fleet's only **BLOCKED** to **VALIDATED**, and the malicious-OCI-image vector now has a no-setup fire. The round-1 blocker (host kernel resolves vdev paths in the host mount namespace; shell-less appliance precludes an admin bind mount) is defeated **without any bind**: the container's own rootfs necessarily exists on the host at the predictable path `/var/lib/incus/storage-pools/local/containers/<ct>/rootfs/`, so the image's payload at `/opt/d77.img` is host-resolvable by construction. A malicious OCI image launched as a **default unprivileged** container (default profile only — no `security.privileged`, no device add, no bind) carries a static raw `ZFS_IOC_POOL_TRYIMPORT` PoC (hand-packed nvlist, libzfs bypassed; `linux-research/incusos-spike/oz4-tryimport.c`, zg-poolop.c lineage) pointed at that host path; the ioctl is issued by **non-root uid 1000**, authorized via an image-controlled file capability (`cap_sys_admin+ep` on the payload binary — an attacker image property, not an admin concession; verified differentially: cap cleared → `EPERM`). The armed import **wedges the host kernel's ZFS load path and storage stack** (`incusd` unresponsive, ioctl never returns; reproduced on a fresh kernel), while the structurally identical clean control imports in <1s. Negative controls (wrong path, nonexistent path, cleared cap) all fail as expected. On this kernel the overflow surfaces as a **wedge/storage-DoS** rather than TrueNAS's instant GPF-panic (heap-layout dependent); no root shell is claimed. Attacker preconditions: get the victim to launch the image as a default container; knowledge of the container name; nothing else. Full verdict and evidence: `linux-research/.fleet-coord/oz4-oci-incusos2-verdict.md`; `linux-research/incusos-spike/runs/20260726-oz4-oci2/evidence/`. - **2026-07-26 (OZ-4 OCI on TrueNAS SCALE, round 3 — VALIDATED with ZERO host-side setup, kernel panic):** the zero-wire rootfs-path vector fires on TrueNAS SCALE 25.04.2.4 as well, upgrading round 2's concession-laden fire. A malicious OCI image launched as a **default unprivileged** Incus container (dir storage backend, default profile only — no privileged flag, no device add, no bind, no host shell) carries the armed pool at `/opt/d77.img`, a static raw-ioctl PoC (`oz4ti`, zg-poolop/xpl-107-poolop lineage), and a **NATIVE-encoded** config nvlist naming the host-side rootfs path (`/var/lib/incus/storage-pools/default/containers/<name>/rootfs/opt/d77.img`, fully derivable from appliance defaults + the attacker-chosen container name). The import is issued by a **non-root** nested-userns user (host `UID: 2147001001`). The armed import **panicked the production kernel** (GPF in `__kmalloc` on `spa_tryimport → spa_load → spa_ld_load_special_directories`, corrupted SLUB freelist; crashing task `Comm: oz4ti`), while the structurally identical clean control imported `rc=

QNAP QZFS static analysis validates\nZ1/Z2/dnode-bonus S3\n  and gang overrun, and BLOCKS log-spacemap S4 (feature absent). The\nupstream\n  patch audit confirms every OZ finding remains **UNFIXED** at upstream\nmaster\n  HEAD `3020c18c` (2026-07-24); only OZ-7 has an open, contested PR\n(#18620).\n  Full audit:\n[`research/upstream-patch-audit.md`](../research/upstream-patch-audit.md).\n- **2026-07-25 (OZ-4 on Proxmox VE):** the Proxmox VE 8.x OZ-4 cell is\nupgraded\n  from provisional to a confirmed dynamic verdict. On `6.8.12-37-pve` /\n  OpenZFS `2.2.10-pve1`, importing the armed dnode-bonus pool (`dn_bonuslen=\n  0x400`, `zfs-77-d77-s3v2.img`) **from inside the delegated LXC container**\n  (CT100 with the OZ-1 verified `/dev/zfs` passthrough) fired the\n  `dbuf_read_bonus` overflow on `spa_tryimport \u2192 spa_load \u2192\n  spa_ld_trusted_config` and crashed the kernel (NULL-deref in `strcmp`\nduring\n  `vdev_open_children_impl`; host-side corroboration showed SLUB\n`LIST_POISON`\n  heap corruption in `dbuf_sync_list`). OZ-4 is therefore **VIABLE from the\n  delegated/privileged container** and **BLOCKED by default** (default\n  unprivileged LXC has no `/dev/zfs`). A container\u2192root shell was not\n  reproduced on the stock appliance (release kernel faults\ndeterministically;\n  no KASLR leak). Full verdict and evidence:\n  `linux-research/.fleet-coord/oz4-proxmox-verdict.md`;\n\n`linux-research/appliance-harness/proxmox-ve/runs/20260725T150254Z/evidence/`.\n- **2026-07-25 (OZ-4 on Unraid):** the Unraid 7.3.0 OZ-4 cell is upgraded\nfrom\n  provisional to a confirmed dynamic verdict. On `6.18.29-Unraid` / OpenZFS\n  `2.4.1-1`, importing the inflated-bonus pool (`dn_bonuslen=0x1000`,\n  `zfs-77-d77-s3v3.img`) from a `--privileged` Docker container fails\n  `insufficient replicas` while the structurally identical clean control\n  imports ONLINE; the kernel survives (silent heap corruption, no\npanic/Oops).\n  OZ-4 is therefore **VIABLE from `--privileged`** and **BLOCKED** by\ndefault\n  and `--device /dev/zfs` (no `/dev/zfs` / no `CAP_SYS_ADMIN`). A\ncontainer\u2192root\n  shell was not pursued (requires heap grooming + KASLR bypass). Full\nverdict\n  and evidence: `linux-research/.fleet-coord/oz4-unraid-verdict.md`;\n  `linux-research/appliance-harness/unraid/runs/20260725T150925Z/evidence/`.\n- **2026-07-25 (OZ-4 OCI delivery on IncusOS):** an OCI image\n  (`oz4-delivery:latest`) carrying the armed pool (`d77.img`) was built with\n  podman, repacked as an Incus image, and launched as a default unprivileged\n  Incus container on IncusOS `202607192224` (OpenZFS `2.4.3-1`). The\ncontainer\n  received `/dev/zfs` and the ioctls were authorized (OZ-1 reachability\n  **VIABLE**), but the host kernel could not open the file vdev at the\n  container-relative path (`/opt/d77.img`), so the OZ-4 overflow never fired\n  (**BLOCKED** for the in-container E2E fire). IncusOS\u0027s shell-less design\n  removes the host-side bind-mount escape hatch that made the fire possible\non\n  Proxmox VE. Full verdict and evidence:\n  `linux-research/.fleet-coord/oz4-oci-incusos-verdict.md`;\n  `linux-research/incusos-spike/runs/20260725-oz4-oci/evidence/`.\n- **2026-07-25 (OZ-4 OCI delivery on TrueNAS SCALE):** the same OCI image\n  (`oz4-delivery:latest`) was launched as a default unprivileged Incus\n  container on TrueNAS SCALE 25.04.2.4. The entrypoint auto-fired the import\n  ioctl, but the host kernel could not open the container-relative file vdev\n  (`/opt/d77.img`), so the OZ-4 overflow never fired (**BLOCKED**). This\n  refines the prior TrueNAS host-side **VIABLE** verdict: the overflow is\n  reachable from a host path, but not from a self-contained OCI image in a\n  default container. Full verdict and evidence:\n  `linux-research/.fleet-coord/oz4-oci-truenas-verdict.md`;\n\n`linux-research/appliance-harness/truenas-scale/runs/20260725T190000Z/evidence/`.\n- **2026-07-25 (OZ-4 on TrueNAS):** the Dynamically tested appliances table\n  gains an **OZ-4 column**. TrueNAS SCALE 25.04.2.4 (running OpenZFS\n  `2.3.0-1`) is **VIABLE** for OZ-4 from the default unprivileged container:\n  the armed dnode-bonus pool imported ONLINE with no error erevent\n(oversized\n  `dn_bonuslen` accepted, not rejected) on the production non-KASAN kernel,\n  and the same image fired `Write of size 1024 in dbuf_read_impl` via\n  `spa_tryimport` under KASAN. The kernel survives the corruption; a\n  container\u2192root shell is not demonstrated (neighbor-lottery + KASLR, as in\n  the 77b campaign). Proxmox VE and Unraid OZ-4 cells are marked\n**BLOCKED** by\n  default pending their sibling fleet validation tasks. Full verdict and\n  evidence path: `linux-research/.fleet-coord/oz4-truenas-verdict.md`.\n- **2026-07-25 (OZ-4 OCI delivery, round 2 \u2014 VALIDATED on TrueNAS SCALE and\n  Unraid):** the malicious-OCI-image vector is upgraded from **BLOCKED** to\n  **VALIDATED** on two appliances. The round-1 blocker was that the host\n  kernel\u0027s `vdev_file_open` resolves vdev paths in the host mount namespace,\n  so a container-internal `/opt/d77.img` is never opened. Round 2 defeats\nthis\n  with an **identical-path host bind mount** (the image entrypoint stages\nits\n  embedded armed pool onto a bind-mounted host path visible at the same\n  absolute path in both namespaces, then imports from that path). On\n**TrueNAS\n  SCALE 25.04.2.4** the vector fires from a **default unprivileged** Incus\n  container (no `security.privileged`, no explicit device add \u2014 only the\n  default `/dev/zfs`, an identical-path `disk` bind, and a `1777` host\nstaging\n  path): the armed import **panicked the production kernel** (GPF in\n  `__kmalloc` on the `spa_tryimport \u2192 spa_config_generate` path, crashing\ntask\n  `Comm: zpool` as the container\u0027s mapped uid in `ZFS_IOC_POOL_TRYIMPORT`),\n  while the structurally identical clean control imported ONLINE. On\n**Unraid\n  7.3.0** the image-carried payload fires via `docker run --privileged` (the\n  required and sufficient capability); the negative control showed the bind\n  mount is not even required under Unraid\u0027s `vfs` storage driver. The Unraid\n  result is **expected behavior** \u2014 a `--privileged` container holds full\nhost\n  capabilities by design \u2014 and is retained for matrix completeness only; it\nis\n  not scored as a finding. The TrueNAS round-2 fire is the significant\nresult,\n  but note its two deployment concessions: an identical-path host bind and a\n  world-writable host staging path must be granted to the container (as an\napp\n  manifest\u0027s hostPath grant would provide). The Unraid kernel survives\n(silent\n  corruption \u2192 `insufficient replicas`); the TrueNAS\n  crash is a **reliable image-delivered container\u2192host-kernel DoS** \u2014 no\nheap\n  grooming required. IncusOS remains **BLOCKED** for this vector (shell-less\n  appliance; no host bind-mount escape hatch). Full verdicts and evidence:\n  `linux-research/.fleet-coord/oz4-oci-truenas2-verdict.md`,\n  `linux-research/.fleet-coord/oz4-oci-unraid-verdict.md`;\n\n`linux-research/appliance-harness/truenas-scale/runs/20260725T193000Z/evidence/`,\n  `linux-research/appliance-harness/unraid/runs/20260725T194343Z/evidence/`.\n- **2026-07-26 (OZ-4 OCI on IncusOS, round 2 \u2014 VALIDATED with ZERO host-side\n  setup):** IncusOS flips from the fleet\u0027s only **BLOCKED** to\n**VALIDATED**,\n  and the malicious-OCI-image vector now has a no-setup fire. The round-1\n  blocker (host kernel resolves vdev paths in the host mount namespace;\n  shell-less appliance precludes an admin bind mount) is defeated **without\n  any bind**: the container\u0027s own rootfs necessarily exists on the host at\nthe\n  predictable path\n`/var/lib/incus/storage-pools/local/containers/\u003cct\u003e/rootfs/`,\n  so the image\u0027s payload at `/opt/d77.img` is host-resolvable by\nconstruction.\n  A malicious OCI image launched as a **default unprivileged** container\n  (default profile only \u2014 no `security.privileged`, no device add, no bind)\n  carries a static raw `ZFS_IOC_POOL_TRYIMPORT` PoC (hand-packed nvlist,\n  libzfs bypassed; `linux-research/incusos-spike/oz4-tryimport.c`,\nzg-poolop.c\n  lineage) pointed at that host path; the ioctl is issued by **non-root uid\n  1000**, authorized via an image-controlled file capability\n  (`cap_sys_admin+ep` on the payload binary \u2014 an attacker image property,\nnot\n  an admin concession; verified differentially: cap cleared \u2192 `EPERM`). The\n  armed import **wedges the host kernel\u0027s ZFS load path and storage stack**\n  (`incusd` unresponsive, ioctl never returns; reproduced on a fresh\nkernel),\n  while the structurally identical clean control imports in \u003c1s. Negative\n  controls (wrong path, nonexistent path, cleared cap) all fail as expected.\n  On this kernel the overflow surfaces as a **wedge/storage-DoS** rather\nthan\n  TrueNAS\u0027s instant GPF-panic (heap-layout dependent); no root shell is\n  claimed. Attacker preconditions: get the victim to launch the image as a\n  default container; knowledge of the container name; nothing else. Full\n  verdict and evidence:\n  `linux-research/.fleet-coord/oz4-oci-incusos2-verdict.md`;\n  `linux-research/incusos-spike/runs/20260726-oz4-oci2/evidence/`.\n- **2026-07-26 (OZ-4 OCI on TrueNAS SCALE, round 3 \u2014 VALIDATED with ZERO\n  host-side setup, kernel panic):** the zero-wire rootfs-path vector fires\non\n  TrueNAS SCALE 25.04.2.4 as well, upgrading round 2\u0027s concession-laden\nfire.\n  A malicious OCI image launched as a **default unprivileged** Incus\ncontainer\n  (dir storage backend, default profile only \u2014 no privileged flag, no device\n  add, no bind, no host shell) carries the armed pool at `/opt/d77.img`, a\n  static raw-ioctl PoC (`oz4ti`, zg-poolop/xpl-107-poolop lineage), and a\n  **NATIVE-encoded** config nvlist naming the host-side rootfs path\n\n(`/var/lib/incus/storage-pools/default/containers/\u003cname\u003e/rootfs/opt/d77.img`,\n  fully derivable from appliance defaults + the attacker-chosen container\n  name). The import is issued by a **non-root** nested-userns user (host\n  `UID: 2147001001`). The armed import **panicked the production kernel**\n  (GPF in `__kmalloc` on `spa_tryimport \u2192 spa_load \u2192\n  spa_ld_load_special_directories`, corrupted SLUB freelist; crashing task\n  `Comm: oz4ti`), while the structurally identical clean control imported\n  `rc="

Title
Re: Security advisory: multiple vulnerabilities including Default-credential RCE, Pre-authentication root RCE in atvise SCADA 3.13.0 (atvise GmbH / Bachmann Visutec)
Summary
Reference: https://seclists.org/fulldisclosure/2026/Aug/5 I tested both vulnerabilities against a clean installation of atvise SCADA 3.13.0. Results differ between the two findings. --- Vulnerability 1 (OPC UA pre-authentication root RCE, CVSS 9.8) - NOT REPRODUCIBLE The ActivateSession step - identified as the authentication bypass entry point - returns BadUserAccessDenied: WebMI login(root, bogus) -> 200 {"error":-1,"errorstring":"Invalid Session or Digest"} [+] root has a strong password (bogus login rejected) [Step 1] OPC UA 4840 ActivateSession(root, bogus) -- authentication bypass ServiceFault (BadUserAccessDenied, diagnostics: DiagnosticInfo( SymbolicId=None, NamespaceURI=None, Locale=None, LocalizedText=None, AdditionalInfo=None, InnerStatusCode=None, InnerDiagnosticInfo=None)) from server received in response to ActivateSessionRequest The OPC UA backend rejects the bogus password and does not yield a superuser session, contrary to the advisory's claim that logonSessionUser never calls the password-verification function. Note for anyone attempting independent reproduction: the advisory's license note discloses that the research was conducted against a binary-patched installation (patch 5: isLicensed() forced to 1; patch 6: session-count bypass). Whether OPC UA authentication behaviour differs between the patched binary and an unmodified licensed installation remains the open question. If the 0day Rubbish Research Team can clarify whether the ActivateSession step was verified against the original unpatched binary, that would help resolve the discrepancy. --- Vulnerability 2 (WebMI default-credential RCE, CVSS 8.8) - REPRODUCIBLE Confirmed. login(root, <any value>) returns {"username":"root"} on a factory-default installation. The handleLogin 'password not set' branch behaves exactly as described. Setting a strong root password via changepassword closes the bypass. Mit freundlichen Grüßen With kind regards Ing.

Results differ between the two \nfindings.\n\n---\n\nVulnerability 1 (OPC UA pre-authentication root RCE, CVSS 9.8) - NOT REPRODUCIBLE\n\nThe ActivateSession step - identified as the authentication bypass entry point - returns BadUserAccessDenied:\n\n    WebMI login(root, bogus) -\u003e 200 {\"error\":-1,\"errorstring\":\"Invalid Session or Digest\"}\n        [+] root has a strong password (bogus login rejected)\n    [Step 1] OPC UA 4840 ActivateSession(root, bogus) -- authentication bypass\n    ServiceFault (BadUserAccessDenied, diagnostics: DiagnosticInfo(\n      SymbolicId=None, NamespaceURI=None, Locale=None,\n      LocalizedText=None, AdditionalInfo=None,\n      InnerStatusCode=None, InnerDiagnosticInfo=None))\n    from server received in response to ActivateSessionRequest\n\nThe OPC UA backend rejects the bogus password and does not yield a superuser session, contrary to the advisory\u0027s claim \nthat logonSessionUser never calls the password-verification function.\n\nNote for anyone attempting independent reproduction: the advisory\u0027s license note discloses that the research was \nconducted against a binary-patched installation (patch 5: isLicensed() forced to 1; patch 6: session-count bypass). \nWhether OPC UA authentication behaviour differs between the patched binary and an unmodified licensed installation \nremains the open question. If the 0day Rubbish Research Team can clarify whether the ActivateSession step was verified \nagainst the original unpatched binary, that would help resolve the discrepancy.\n\n---\n\nVulnerability 2 (WebMI default-credential RCE, CVSS 8.8) - REPRODUCIBLE\n\nConfirmed. login(root, \u003cany value\u003e) returns {\"username\":\"root\"} on a factory-default installation. The handleLogin \n\u0027password not set\u0027 branch behaves exactly as described. Setting a strong root password via changepassword closes the \nbypass.\n\nMit freundlichen Gr\u00fc\u00dfen\nWith kind regards\n\nIng.
