The OSLC integration feature in the Web component in IBM Rational ClearQuest 7.1 before 7.1.2.15, 8.0.0 before 8.0.0.12, and 8.0.1 before 8.0.1.5 provides different error messages for failed login attempts depending on whether the username exists, which allows remote attackers to enumerate account names via a series of requests.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
