- 漏洞描述

Check Point FireWall-1 contains a flaw thta may allow a remote attacker to bypass authentication. The issue is due to a flaw in the OPSEC (FWN1) authentication implementation. If an attacker intiates an OPSEC connection the server sends a random number, hash of the number and a shared secret key. If the attacker takes this information and sends it back to the server, it will not require further authentication.
