Description:
Darren Bounds has reported a security issue in Cisco Secure ACS, which can be exploited by malicious people to bypass certain security restrictions.
The problem is caused due to the web-based management interface handling session management in an insecure way based on the assigned service port and the client's IP address. This can be exploited to bypass the user authentication and gain full administrative access to the web interface by guessing the assigned service port to a logged in administrative user.
Successful exploitation requires that the attacker uses the same IP address as the logged in administrative user.
The security issue has been reported in version 4.0 for Windows. Other versions may also be affected.
Solution:
Only connect to the web-based management interface from dedicated management systems.
