Multiple Cisco Products SNORT HTTP Detection Engine File Policy Bypass Vulnerability

view advisory published 2020-10-21

Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass a configured File Policy for HTTP. The vulnerability is due to incorrect detection of modified HTTP packets used in chunked responses. An attacker could exploit this vulnerability by sending crafted HTTP packets through an affected device. A successful exploit could allow the attacker to bypass a configured File Policy for HTTP packets and deliver a malicious payload. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
