Subject:  Symantec Enterprise Firewall Secure Webserver info leak


Advanced IT-Security Advisory #02-10-2002

http://www.ai-sec.dk/

Issue:
======
Symantec Enterprise Firewall Secure Webserver info leak


Problemdescription:
===================
There exists a problem in Simple, secure webserver 1.1 which is shipped with Raptor Firewall 6.5 (among others), in which an attacker
 can connect to the proxyserver from the outside, and issue a 
CONNECT to IP-addresses on the inside interface, and thereby determine if there are hosts present or not by inspecting the errormessage.
 This problem lets an attacker map out the entire topology of a 
client from the outside. 

Symantec has addressed this issue as a collateral problem in an earlier security update for the Symantec Enterprise Firewall. The
 Symantec Enterprise Firewall is not vulnerable to this concern if 
patched fully up-to-date.

Versions affected:
==================
Raptor Firewall 6.5 (Windows NT)
Raptor Firewall V6.5.3 (Solaris)
Symantec Enterprise Firewall 6.5.2 (Windows 2000 and NT)

Solutions:
============
Apply official patch from Symantec

Patch:
======
http://www.symantec.com/techsupp

Vendorstatus:
=============
Symantec was contacted 27. August 2002. Symantec promptly tested and confirmed our findings. However, Symantec claims that this issue
 was fixed in a patch released late summer 2002.
