A vulnerability in Cisco Hosted Collaboration Solution could allow an unauthenticated, remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability is due to insufficient validation of a user-supplied value. An attacker could exploit this vulnerability by convincing a user to click a specific link. A successful exploit could allow the attacker to execute arbitrary script or HTML in the user's session, which could be used to access sensitive browser-based information.

Cisco has confirmed the vulnerability; however, software updates are not available.

To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
