Loss of Integrity
Exploit Public

- 漏洞描述

Check Point FireWall-1 contains a flaw that may allow a remote attacker to authenticate against the server. The issue is due to a weakness in the FWA1 protocol. An attacker may be able to replay a modified challenge from a server to authenticate to the firewall. Despite authenticating, the attacker would not have the encryption key necessary to maintain communication or execute commands.
