"The remote Cisco Wireless LAN Controller (WLC) is affected by an
information disclosure vulnerability known as POODLE. The
vulnerability is due to the way SSL 3.0 handles padding bytes when
decrypting messages encrypted using block ciphers in cipher block
chaining (CBC) mode. MitM attackers can decrypt a selected byte of a
cipher text in as few as 256 tries if they are able to force a victim
application to repeatedly send the same data over newly created SSL
3.0 connections.");
