The time-based ACL implementation on Cisco Adaptive Security Appliances (ASA) devices, and in Cisco Firewall Services Module (FWSM), does not properly handle periodic statements for the time-range command, which allows remote attackers to bypass intended access restrictions by sending network traffic during denied time periods, aka Bug IDs CSCuf79091 and CSCug45850.
Weaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
