Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass the configured file policies on an affected system. The vulnerability is due to errors in how the Snort detection engine handles specific HTTP responses. An attacker could exploit this vulnerability by sending crafted HTTP packets that would flow through an affected system. A successful exploit could allow the attacker to bypass the configured file policies and deliver a malicious payload to the protected network.
The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product.
The product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource.
