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.

Security readout for executives and security teams

Check Point Firewall-1's session agent (versions 3.0 through 4.1) revealed whether a login failure was due to a wrong username or a wrong password. Attackers could use that difference to build a list of real user accounts and then guess passwords. The issue is old and affects long-unsupported software, but the underlying lesson about consistent error messages still matters. Exposure is limited today because Check Point Firewall-1 3.0 through 4.1 is legacy software far past end-of-life. Any organization still operating these versions with the session agent authentication reachable from untrusted networks would be exposed to username discovery and password guessing. Low priority for modern environments. Only material if legacy Check Point Firewall-1 3.0-4.1 systems remain in use; in that case, prioritize retiring or isolating them as part of standard legacy-asset remediation, not as an emergency response. Mitigation focus: Retire or upgrade any Check Point Firewall-1 3.0 through 4.1 instances still in production.; Restrict session agent authentication endpoints to trusted management networks only.; Consult Check Point vendor guidance; no specific fix is named in the cited sources..
