Customers should refer to Cisco bug ID CSCui30266 for the most complete list of affected product versions.
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary script or HTML code in the user's browser in the security context of the affected application. This action could allow the attacker to steal sensitive browser-based information, including authentication cookies and recently submitted data, or to take actions on the site as the affected user.
The affected software fails to perform sufficient validation and sanitation of user-supplied input when processing crafted URLs before returning the input to the user's browser session. When returned to the browser, the malicious parameter may execute in the security context of the affected site.
An unauthenticated, remote attacker could exploit this vulnerability by convincing a user of the web interface to follow a crafted URL that is designed to submit malicious input to the vulnerable script. The script may return that input to the user's browser without proper sanitation and render the input in the security context of the affected site. The attacker could include arbitrary script or HTML code that could allow the attacker to access sensitive browser-based information or execute actions on the site with the privileges of the user.
