Description

A vulnerability in the protocol detection component of Cisco Firepower Threat Defense Software, Cisco FirePOWER Services Software for ASA, and Cisco Firepower Management Center Software could allow an unauthenticated, remote attacker to bypass filtering protections. The vulnerability is due to improper detection of the initial use of a protocol on a nonstandard port. An attacker could exploit this vulnerability by sending traffic on a nonstandard port for the protocol in use through an affected device. An exploit could allow the attacker to bypass filtering and deliver malicious requests to protected systems that would otherwise be blocked. Once the initial protocol flow on the nonstandard port is detected, future flows on the nonstandard port will be successfully detected and handled as configured by the applied policy.

Affected configurations

• cisco firepower services software for asa • cisco secure firewall management center (>= 2.9.12 <= 2.9.12.15) • cisco secure firewall management center (>= 2.9.13 <= 2.9.13.6) • cisco secure firewall management center (>= 2.9.14.0 <= 2.9.14.5) • cisco secure firewall management center 2.9.15 • cisco secure firewall management center 2.9.16 • cisco secure firewall threat defense
