Technical details
A reflected cross-site scripting (XSS) vulnerability exists in the web-based management interface due to insufficient input validation. An unauthenticated, remote attacker can conduct the attack by crafting a malicious link and persuading a user to click it; successful exploitation allows arbitrary script execution in the context of the interface. Cisco has released fixed versions for both affected products.
