Cisco AnyConnect Secure Mobility Client < 3.1(5187) (POODLE)

low Nessus Plugin ID 78676

Language:

Synopsis

The remote host is affected by an information disclosure vulnerability.

Description

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.

Solution

Upgrade to Cisco AnyConnect Secure Mobility Client 3.1(5187) or later.

Alternatively, apply the workaround provided by Microsoft.
