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.
This issue was found and fixed a while ago as I just learned from Check
Point:
This vulnerability was published on BugTraq. It was discovered in the past
and fixed. The following sentence was added to Release Notes: .HTTP
protocol inspection has been enhanced..
The following versions and later are not vulnerable:
NG AI R54 HFA_414
NG AI R55 HFA_12
NG AI R55W HFA_3
NGX R60
NGX R60A
NGX R61
VSX NG AI HFA_02
VSX NGX
Interspect 2.0
Interspect NGX
Connectra 2.0
Connectra NGX R60
Connectra NGX R61
