Cisco Wireless LAN Controller (WLC) ACL weak security
|cisco-wlc-acl-weak-security (33611)||Medium Risk|
Cisco Wireless LAN Controller (WLC) could provide weaker than expected security caused by an error when the Access Control List (ACL) is saved. The ACL configuration is saved with an invalid checksum. When the WLC is restarted the ACL fails to load because of an invalid checksum resulting in weaker than expected security.
