Internet Security Systems Security Brief
February 4, 2004
Checkpoint Firewall-1 HTTP Parsing Format String Vulnerabilities
Synopsis:
ISS X-Force has discovered a flaw in the HTTP Application Intelligence
component of Firewall-1. Application Intelligence is a relatively recent
addition to the Firewall-1 product line and functions as an application
proxy between untrusted networks and network servers for the purpose of
detecting and preventing potential attacks. The vulnerabilities also exist
within the HTTP Security Server application proxy that ships with all
versions of Firewall-1 (including those prior to Application Intelligence
releases). The affected components contain several remotely exploitable
format string vulnerabilities.
Impact:
If HTTP Application Intelligence is enabled or the HTTP Security Server is
used, a remote unauthenticated attacker may exploit one of these
vulnerabilities and execute commands under the security context of the
super-user, usually "SYSTEM", or "root". This attack may lead to direct
compromise of the Firewall-1 server.
Remote attackers may leverage this attack to successfully compromise heavily
hardened networks by modifying or tampering with the firewall rules and
configuration.
Affected Versions:
Checkpoint Firewall-1 NG-AI R55, R54, including SSL hotfix
Checkpoint Firewall-1 HTTP Security Server included with NG FP1, FP2, FP3
Checkpoint Firewall-1 HTTP Security Server included with 4.1
