Cisco IOS before 15.0(1)XA1 does not clear the public key cache upon a change to a certificate map, which allows remote authenticated users to bypass a certificate ban by connecting with a banned certificate that had previously been valid, aka Bug ID CSCta79031.
The product does not validate, or incorrectly validates, a certificate.
