Description

Check Point FireWall-1 contains a flaw that may disclose sensitive network topology information to a remote attacker. The issue is due to a flaw in the SecuRemote software which creates sessions between remote users and FW-1 modules. When a remote user connects to the system a network topology is transferred to the client, regardless of authentication.

Classification

Location: Remote / Network Access
Attack Type: Information Disclosure
Impact: Loss of Confidentiality
Exploit: Exploit Public
Disclosure: OSVDB Verified
OSVDB: Security Software

Solution

Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround:
1. Set the firewall gateway for VPN, with the "Respond to unauthenticated topology requests" enabled.
2. Set up a sample secuRemote client, and download the site topology.
3. Turn off "Respond to unauthenticated topology requests".
4. Securely distribute the file userc.C from the sample client to all
secuRemote users.

You will need to send out an updated userc.C any time there is a change to
the encryption domain or keying info.
