Updated: Feb 11 2004|
Original Entry Date: Feb 5 2004
Execution of arbitrary code via network, Root access via network|
Fix Available: Yes Vendor Confirmed: Yes |
Version(s): NG-AI R55, R54; NG; 4.1|
Several format string vulnerabilities were reported in Check Point FireWall-1 in the HTTP Application Intelligence component. A remote user can execute arbitrary code on the firewall with SYSTEM or root level privileges.|
Internet Security Systems (ISS) reported that a remote user can submit a specially crafted HTTP request containing format string specifiers to trigger the flaw. Arbitrary code execution is possible, the report said. If code execution is not achieved, all established HTTP sessions will reportedly be dropped.
The HTTP Security Server application proxy is also affected.
The vendor indicates that you are only affected if you use the HTTP security servers.
The vendor was reportedly notified on February 2, 2004.
A remote user can execute arbitrary code on the target system with SYSTEM/root privileges.|
The vendor has issued a fix, applicable to the following releases:|
1. NG FP3 HF2
2. NG with Application intelligence R54
3. NG with Application intelligence R55
4. Other NG based releases (NG FCS, NG FP1, NG FP2 ...).
The fix is available for Software Subscription customers at:

Checkpoint Firewall-1 HTTP Parsing Format String Vulnerabilities
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.
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
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
