Mac OS X : OS X Server < 2.2.5 SSLv3 Information Disclosure (POODLE)

medium Nessus Plugin ID 78599
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote host is missing a security update for OS X Server.

Description

The remote Mac OS X 10.8 host has a version of OS X Server installed that is prior to version 2.2.5. It is, therefore, affected by an information disclosure vulnerability.

An error exists related to the way SSL 3.0 handles padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. A man-in-the-middle 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. This is also known as the 'POODLE' issue.

Solution

Upgrade to Mac OS X Server version 2.2.5 or later.
