Discussion
Cisco User-Changeable Password (UCP) 'CSuserCGI.exe' Multiple Remote Vulnerabilities
Cisco User-Changeable Password (UCP) is prone to multiple remote vulnerabilities, including cross-site scripting and buffer-overflow vulnerabilities.
Exploiting the cross-site scripting issues may help the attacker steal cookie-based authentication credentials and launch other attacks. Exploiting the buffer-overflow vulnerabilities allows attackers to execute code in the context of the affected application, facilitating the remote compromise of affected computers.
The buffer-overflow issues are tracked by Cisco Bug ID CSCsl49180. The cross-site scripting issues are tracked by Cisco Bug ID CSCsl49205.
These issues affect versions prior to UCP 4.2 when running on Microsoft Windows.

Exploit / POC
Cisco User-Changeable Password (UCP) 'CSuserCGI.exe' Multiple Remote Vulnerabilities
An attacker can exploit the cross-site scripting issues by enticing an unsuspecting user to follow a malicious URI.
DSquare Security has developed a working commercial exploit for its D2 Exploitation Pack product. This exploit is not otherwise publicly available or known to be circulating in the wild.
Core Security Technologies has developed a working commercial exploit for its CORE IMPACT product. This exploit is not otherwise publicly available or known to be circulating in the wild.
The following proof-of-concept URI demonstrates one of the buffer-overflow issues:
