Technical details

An authentication bypass vulnerability exists in the Jazz Foundation component of IBM Engineering Lifecycle Management due to incorrect authorization (CWE-863). The flaw allows a remote, unauthenticated attacker to modify server property files. By manipulating these configuration files, an attacker can escalate privileges or bypass authentication mechanisms entirely to gain unauthorized access to the application. The vulnerability is exploitable over the network with low complexity and requires no user interaction. IBM has released interim fixes (iFixes) to address this issue across versions 7.0.3, 7.1.0, and 7.2.0.
