FireWall-1 SecuRemote/SecuClient authentication allows remote users to bypass "timeouts"
|fw1-authentication-bypass-timeouts (8423)||Low Risk|
Check Point FireWall-1 could allow a remote user to bypass firewall restrictions. The "Validation timeout" option in FireWall-1 allows network administrators to set up a restriction, which requires remote users to re-authenticate after a specified time. If a remote user authenticates using SecuRemote or SecuClient, the attacker can then bypass this restriction by modifying the "userc.C" configuration file, which is downloaded during the first time a user authenticates.
No remedy available as of April 1, 2014.
