Cisco Firepower Malware Block Bypass Vulnerability

Advisory ID: cisco-sa-20160330-fp

Revision 1.0

For Public Release 2016 March 30 16:00 UTC (GMT)

+---------------------------------------------------------------------

Summary
=======

A vulnerability in the malicious file detection and blocking features of
Cisco Firepower System Software could allow an unauthenticated, remote
attacker to bypass malware detection mechanisms on an affected system.

The vulnerability is due to improper input validation of fields in HTTP
headers. An attacker could exploit this vulnerability by sending a crafted
HTTP request to an affected system. A successful exploit could allow the
attacker to bypass malicious file detection or blocking policies that are
configured for the system, which could allow malware to pass through the
system undetected.

Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
