CVE-2013-2625

Vulnerability

The vulnerability is an access bypass issue in the object linking mechanism of OTRS Help Desk before versions 3.2.4, 3.1.14, and 3.0.19; OTRS ITSM before versions 3.2.3, 3.1.8, and 3.0.7; and OTRS FAQ before versions 2.2.3, 2.1.4, and 2.0.8. The access rights for linked objects are not properly verified, allowing users to access objects they should not have permission to see [1].

Exploitation

An attacker needs to be an authenticated user of the OTRS system with the ability to view or create linked objects. No special privileges are required beyond regular user access. The attacker can exploit the missing access check by manipulating or viewing linked objects that were linked from other restricted contexts, thereby bypassing the intended access control restrictions.

Impact

Successful exploitation allows an authenticated attacker to bypass access controls and view, and potentially interact with, otherwise restricted objects. This can lead to unauthorized information disclosure and potential modification of data that should be protected. The compromise is within the scope of the OTRS application and does not provide system-level access.

Mitigation

The fix was released in the affected product lines: OTRS Help Desk 3.2.4, 3.1.14, and 3.0.19; OTRS ITSM 3.2.3, 3.1.8, and 3.0.7; and OTRS FAQ 2.2.3, 2.1.4, and 2.0.8. Users should upgrade to these versions or later. No workaround is described in the available references [1].
