TITLE:
Cisco Wireless Control System Vulnerability and Security Issues

SECUNIA ADVISORY ID:
SA24865

VERIFY ADVISORY:
http://secunia.com/advisories/24865/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Exposure of system information, Exposure of
sensitive information, Privilege escalation, System access

WHERE:
>From remote

SOFTWARE:
Cisco Wireless Control System (WCS)
http://secunia.com/product/6332/

DESCRIPTION:
A vulnerability and two security issues have been reported in Cisco
Wireless Control System (WCS), which can be exploited by malicious
users to gain escalated privileges, and by malicious people to
disclose sensitive information, bypass certain security restrictions,
or potentially compromise a vulnerable system.

1) WCS includes a fixed username and password for backup operations
via FTP. This can be exploited to read from and write to arbitrary
files on affected systems.

Successful exploitation potentially allows the server to be
compromised, but requires knowledge of other properties of the FTP
server.

The security issue has been reported in WCS prior to version
4.0.96.0.

2) An unspecified error exists in the authentication system, which
can be exploited by an authenticated user to change his account group
membership.

Successful exploitation can allow full administrative control of WCS,
but requires a valid username and password.

The vulnerability is reported in WCS prior to version 4.0.87.0.

3) Certain directories in WCS are not password protected. This can be
exploited to disclose certain system information, e.g. organization of
the network including access point locations.

The security issue is reported in WCS prior to version 4.0.66.0.

SOLUTION:
Update to version 4.0.96.0 or later.

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