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.
