This vulnerability exists because the affected software does not properly validate HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected software. A successful exploit could allow the attacker to delete arbitrary files from the affected system. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
