Description

A vulnerability in the normalization functionality 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 insufficient normalization of a text-based payload. An attacker could exploit this vulnerability by sending traffic that contains specifically obfuscated payloads through an affected device. An exploit could allow the attacker to bypass filtering and deliver malicious payloads to protected systems that would otherwise be blocked.

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
