Subject: Check Point R55W Directory Traversal
Overview
Check Point Firewall-1 R55W contains a hard coded web server, which runs
on TCP port 18264. This server is there to deal with PKI requirements
for Check Point's VPN functionality.
During a routine penetration test of a client, Sec-Tec discovered a
directory traversal vulnerability that allows a potential attacker to
retrieve files from the underlying OS.
This issue is potentially serious for a number of reasons:
1. Check Point's "rule zero" will often by default allow access to this
port for external IP addresses.
2. It would currently seem that there are few restrictions as to what
files can be retrieved via this mechanism (Sec-Tec were able to obtain
the underlying OS' account repository).
Exploit
The issue can be exploited via a web browser using typical hex encoded
directory traversal strings.
Affected Version(s):
Check Point R55W
Check Point R55W HFA1
Check Point R55W HFA2
(Confirmed on Windows 2003 Server platform, other platforms may be
affected.)
Current Status
Check Point have confirmed that this issue was corrected in R55W HFA03.
However, Sec-Tec have been unable to find any publicly available
references to this issue, either within Check Point's knowledge base or
HFA03 release notes.
