The vulnerability is due to improper input validation of the parameters of an HTTP request. An attacker could exploit this vulnerability by intercepting an HTTP request from a user. A successful exploit could allow the attacker to modify the HTTP request to cause the interface to redirect the user to a specific, malicious URL. This type of vulnerability is known as an open redirect attack and is used in phishing attacks that get users to unknowingly visit malicious sites. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
