VAR-200012-0098

Vulnerability from variot - Updated: 2023-12-18 13:16

Check Point Firewall-1 session agent 3.0 through 4.1 generates different error messages for invalid user names versus invalid passwords, which allows remote attackers to determine valid usernames and guess a password via a brute force attack. A vulnerability exists in all versions of the Check Point Session Agent, part of Firewall-1. Session Agent works in such a way that the firewall will establish a connection back to the client machine. Upon doing so, it will prompt for a username, and if the username exists, a password. Upon failure, it will reprompt indefinitely. This allows for a simple brute force attack against the username and password
