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

## 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

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
