Wind River VxWorks 6.6 through vx7 has Session Fixation in the TCP component. This is a IPNET security vulnerability: DoS of TCP connection via malformed TCP options.

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
Vxworks Windriver 6.5 (including) 6.9.4.12 (excluding)
Vxworks Windriver 7.0 (including) 7.0 (including)

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.
