CVE-2023-1250
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Input Validation vulnerability in OTRS AG OTRS (ACL modules), OTRS AG ((OTRS)) Community Edition (ACL modules) allows Local Execution of Code. When creating/importing an ACL it was possible to inject code that gets executed via manipulated comments and ACL-names This issue affects OTRS: from 7.0.X before 7.0.42, from 8.0.X before 8.0.31; ((OTRS)) Community Edition: from 6.0.1 through 6.0.34.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceImproper input validation in the ACL (Access Control List) module of OTRS allows authenticated attackers to inject and execute malicious code through manipulated comments and ACL names when creating or importing ACLs. This is a code injection vulnerability enabling local code execution with the privileges of the OTRS application.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed OTRS versionRun the OTRS system information command or check the version file in the OTRS installation directory. Common methods: accessing Admin > System Administration > System Information in the web interface, or checking /opt/otrs/RELEASE file if installed via package.Affected if The installed version falls within 6.0.1-6.0.34, 7.0.0-7.0.41, or 8.0.0-8.0.30 (unpatched) and is older than the fixed versions 7.0.42, 8.0.31, or 6.0.35.
-
Verify ACL module is enabledCheck the OTRS configuration file (Kernel/Config.pm) or access Admin > Access Control Lists (ACL) in the web interface. Confirm whether ACL functionality has been configured or activated in the system.Affected if The ACL module is actively configured or accessible in the OTRS instance.
-
Inspect existing ACL configurations for injected codeNavigate to Admin > Access Control Lists and review all ACL entries. Examine the ACL names and comments fields for unusual patterns such as shell commands, script tags, semicolons followed by commands, backticks, or other code-like syntax that does not belong to legitimate ACL naming conventions.Affected if Any ACL entry contains suspicious code patterns or unexpected characters in the name or comment fields that suggest injection attempts.
-
Review ACL import activity logsCheck OTRS system logs (Admin > Log) and audit logs for events related to ACL creation, modification, or import. Look for entries indicating recent ACL imports or changes, especially from unexpected users or at unusual times.Affected if There are recent ACL import or creation events that correspond to the timeframe when the vulnerable version was in use, particularly from untrusted administrator accounts.
You are affected if your OTRS version is in the vulnerable range (6.0.x up to 6.0.34, 7.0.x up to 7.0.41, or 8.0.x up to 8.0.30) and the ACL feature is enabled or has been used in your environment.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped7.0.428.0.31
Upgrade OTRS to version 7.0.42+, 8.0.31+, or OTRS Community Edition 6.0.35+. Until patched, restrict ACL management to highly trusted administrators and audit existing ACL configurations for suspicious injected content.
OTRS 7.0.42+ or 8.0.31+ (depending on your current major version)
- 1. Identify the current OTRS installation version by checking the system information or the version file.
- 2. For OTRS 7.0.x versions (< 7.0.42): Upgrade to OTRS 7.0.42 or later.
- 3. For OTRS 8.0.x versions (< 8.0.31): Upgrade to OTRS 8.0.31 or later.
- 4. For ((OTRS)) Community Edition 6.0.x versions (6.0.1 through 6.0.34): Note that Community Edition support may be limited; consider upgrading to a supported OTRS version or contact vendor for specific patch availability.
- 5. After upgrading, verify the ACL functionality still works correctly and test that the input validation is properly sanitizing ACL names and comments.
- 6. Review any imported ACL configurations to ensure no malicious code was previously injected.
