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.
Changelog:
2007-01-18: Added CVE reference.
