IBM Spectrum Protect Operations Center 7.1 and 8.1 could allow a remote attacker to bypass authentication restrictions, caused by improper session validation . By using the configuration panel to obtain a valid session using an attacker controlled IBM Spectrum Protect server, an attacker could exploit this vulnerability to bypass authentication and gain access to a limited number of debug functions, such as logging levels. IBM X-Force ID: 192153.

Weakness

Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.

Affected Software

Name Vendor Start Version End Version
Spectrum_protect_operations_center Ibm 7.1.0.000 (including) 7.1.13.000 (excluding)
Spectrum_protect_operations_center Ibm 8.1.0.000 (including) 8.1.10.200 (excluding)

Extended Description

Such a scenario is commonly observed when:

In the generic exploit of session fixation vulnerabilities, an attacker creates a new session on a web application and records the associated session identifier. The attacker then causes the victim to associate, and possibly authenticate, against the server using that session identifier, giving the attacker access to the user’s account through the active session.
