An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to access sensitive files on the affected system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
