VERIFY ADVISORY:
http://secunia.com/advisories/23617/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass

WHERE:
>From local network

SOFTWARE:
Cisco Clean Access (CCA) 3.x
http://secunia.com/product/5561/
Cisco Clean Access (CCA) 4.x
http://secunia.com/product/13140/

DESCRIPTION:
Cisco has acknowledged a security issue in Cisco Clean Access, which
can be exploited by malicious users to bypass certain security
restrictions.

The problem is that the shared secret can't be changed after the
initial setup and is the same on all affected devices.

Successful exploitation may allow administrative access to a Cisco
Access Server, but requires that the attacker is able to establish
TCP connections to the target.

The security issue is reported in versions 3.6.x - 3.6.4.2 and 4.0.x
- 4.0.3.2.

SOLUTION:
Update to version 3.6.4.3, 4.0.4 and 4.1.0 or apply patch
Patch-CSCsg24153.tar.gz.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
