Multiple Cisco products are affected by a vulnerability with TCP Fast Open
(TFO) when used in conjunction with 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 the
HTTP payload if it is contained at least partially within the TFO
connection handshake. An attacker could exploit this vulnerability by
sending crafted TFO packets with an HTTP payload through an affected
device. A successful exploit could allow the attacker to bypass configured
file policy for HTTP packets and deliver a malicious payload.
