"The remote host has a version of Cisco AnyConnect prior to 3.1(5187).
It is, therefore, 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. A MitM attacker 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.");
