TITLE:
Cisco Secure ACS Session Management Security Issue

SECUNIA ADVISORY ID:
SA20816

VERIFY ADVISORY:
http://secunia.com/advisories/20816/

CRITICAL:
Less critical

IMPACT:
Security Bypass

WHERE:
From local network

SOFTWARE:
Cisco Secure ACS 4.x
http://secunia.com/product/10635/

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.
