Summary

The 'established' command on the Cisco PIX firewall allows connections from one host to arbitrary ports of a target host if an alternative conduit has already been allowed. This can lead to administrators configuring less restrictive access controls than intended if they do not understand this functionality.

Risk Assessment

Organizations may be exposed to unauthorized access to services if administrators improperly configure access policies, potentially leading to security breaches.

Recommendation

It is recommended to thoroughly train administrators on the operation of the 'established' command and to review and adjust access policies to ensure an appropriate level of security.
