Vulnerability from github – Published: 2025-11-13 06:30 – Updated: 2025-11-13 06:30
VLAI
Details

The LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes plugin for WordPress is vulnerable to privilege escalation. This is due to the plugin not properly validating a user's identity prior to allowing them to modify their own role via the REST API. The permission check in the update_item_permissions_check() function returns true when a user updates their own account without verifying the role changes. This makes it possible for authenticated attackers, with student-level access and above, to escalate their privileges to administrator by updating their own roles array via a crafted REST API request. Another endpoint intended for instructors also provides an attack vector. Affected version ranges are 3.5.3-3.41.2, 4.0.0-4.21.3, 5.0.0-5.10.0, 6.0.0-6.11.0, 7.0.0-7.8.7, 8.0.0-8.0.7, 9.0.0-9.0.7, 9.1.0.

GHSA-94PW-C6M8-P9P9

Vulnerability from github – Published: 2026-03-30 18:52 – Updated: 2026-04-10 17:20
VLAI
Summary
OpenClaw: Gateway operator.write Can Reach Admin-Class Channel Allowlist Persistence via chat.send
Details

Fixed in OpenClaw 2026.3.24, the current shipping release.

Summary

The shared /allowlist command persists channel authorization config through writeConfigFile(...) but does not re-validate gateway client scopes for internal gateway callers. Because chat.send is intentionally reachable to operator.write callers and still creates a generic command-authorized internal context, an authenticated write-scoped gateway client can indirectly mutate channel allowFrom and groupAllowFrom policy that direct config.patch correctly reserves to operator.admin.

This is not just a generic code smell. The current code already shows the intended boundary by adding sink-side internal admin checks to shared /config and /plugins writes, but /allowlist was left behind.

Details

The gateway's documented scope split is clear:

  • chat.send is a write-scoped action.
  • direct config mutation is an admin-scoped action.

The vulnerable path is:

  1. A gateway client authenticates with operator.write.
  2. The client calls chat.send, which is intentionally allowed for that scope.
  3. chat.send builds an internal message context with CommandAuthorized: true and carries GatewayClientScopes into the reply pipeline.
  4. resolveCommandAuthorization(...) converts that internal message into isAuthorizedSender=true in the common case where no stricter commands.allowFrom override is configured.
  5. /allowlist add|remove accepts that generic command authorization and proceeds into its config-backed edit path.
  6. The handler clones the parsed config, calls plugin.allowlist.applyConfigEdit(...), validates the result, and persists it with writeConfigFile(validated.config).
  7. No sink-side check requires operator.admin before the persistent write occurs.

That creates a direct control-plane mismatch:

  • config.patch rejects the same caller with missing scope: operator.admin.
  • /allowlist add dm ... or /allowlist add group ... reached through chat.send can still rewrite channel authorization state.

Impact

  • A gateway client intentionally limited to operator.write can persist first-party channel authorization policy.
  • The caller can widen DM or group allowlists for channels using the shared /allowlist plumbing.
  • This weakens the repo's documented control-plane privilege split between ordinary write actions and admin-only persistent authorization mutation.

Remediation

1) Add the Missing Sink-Side Internal Admin Check to /allowlist

Mirror the existing hardened pattern from /config and /plugins.

Before any config-backed /allowlist add|remove write, require:

  • operator.admin for internal gateway channels

This should happen before plugin.allowlist.applyConfigEdit(...) and before writeConfigFile(...).

2) Keep Pairing-Store and Config-Write Policy Checks, but Do Not Treat Them as Scope Enforcement

configWrites policy and pairing-store behavior are useful secondary controls, but they do not replace the missing privilege check between operator.write and operator.admin.

Vulnerability from github – Published: 2025-11-26 03:30 – Updated: 2025-11-26 03:30
VLAI
Details

The RupsMon.exe service executable in UPSilon 2000 has insecure permissions, allowing the 'Everyone' group Full Control. A local attacker can replace the executable with a malicious binary to execute code with SYSTEM privileges or simply change the config path of the service to a command; starting and stopping the service to immediately achieve code execution and privilege escalation

Mitigation MIT-1
Architecture and Design Operation

Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.

Mitigation MIT-48
Architecture and Design

Strategy: Separation of Privilege

Follow the principle of least privilege when assigning access rights to entities in a software system.

Mitigation MIT-49
Architecture and Design

Strategy: Separation of Privilege

Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.

CAPEC-122: Privilege Abuse

An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.

CAPEC-233: Privilege Escalation

An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.

CAPEC-58: Restful Privilege Elevation

An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
