CVE-2026-53804: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Centuran Consulting OTRS Community Edition
OTRS Community Edition contains an authenticated OS command injection vulnerability in its PGP encryption module. This flaw allows administrators to execute arbitrary operating system commands by providing crafted values for the PGP binary path and command options. The vulnerability arises because administrator-supplied configuration values are concatenated without proper sanitization into shell commands. Exploitation occurs during normal ticket operations after the malicious configuration is deployed, running commands as the web server process user. The affected versions are up to and including 6.0.41. The vulnerability has a high severity with a CVSS score of 8.6.
AI Analysis
Technical Summary
CVE-2026-53804 is an authenticated OS command injection vulnerability in Centuran Consulting's OTRS Community Edition, specifically in the PGP encryption module. Administrators can supply crafted configuration values for the PGP binary path and command options that are concatenated unsafely into shell commands. This allows arbitrary command execution as the web server user during normal ticket operations after deployment of the malicious configuration. The vulnerability affects versions up to and including 6.0.41. No official patch or remediation guidance is currently provided.
Potential Impact
Successful exploitation allows an authenticated administrator to execute arbitrary operating system commands with the privileges of the web server process. This can lead to full system compromise or unauthorized actions on the server hosting OTRS Community Edition. The vulnerability is high severity due to the potential for significant impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrator access to trusted personnel only and review configuration changes carefully to prevent injection of malicious command parameters.
