AI Analysis
Technical Summary
This vulnerability arises from improper permission handling (CWE-276) in OTRS External Interface and the ConfigItem List module. Authenticated customers can query CI information if CMDB is enabled and CustomerGroupSupport is active. Affected versions include OTRS 7.0.x, 8.0.x, 2023.x, 2024.x, 2025.x, and 2026.x prior to 2026.4.x. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring low privileges and user interaction, with limited confidentiality impact and no integrity or availability impact.
Potential Impact
An authenticated customer with access to the system can query configuration item information that should be restricted, potentially exposing sensitive configuration data. The impact is limited to confidentiality with no effect on integrity or availability. There are no known exploits in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is indicated in the available data. Users should verify if they have CMDB enabled and CustomerGroupSupport active, as these conditions are required for the vulnerability to be exploitable. Monitor vendor communications for updates on patches or mitigations.
