"According to its self-reported version, Cisco IP Phone Stored Cross-Site Scripting may be affected by a cross-site
scripting (XSS) vulnerability. Due to insufficient validation of user-supplied input, an authenticated, remote attacker
can conduct an XSS attacker against a user of the interface on the affected device. A successful exploit could allow
the attacker to execute arbitrary script code in the context of the affected interface or access sensitive,
browser-based information. To exploit this vulnerability, the attacker must have valid credentials to access
the web-based management interface of the affected device.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.");
