JBossWS Endpoint Uses Unsafe Encryption

medium Nessus Plugin ID 66190
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

A Java-based web service running on the remote host uses an unsafe encryption method.

Description

The W3C XML Encryption Standard, implemented in JBossWS and used by one or more endpoints on the remote host, contains a design error. The design error allows unauthenticated, remote attackers to decrypt captured SOAP responses via a chosen-ciphertext attack. This issue affects all block ciphers used in cipher-block chaining (CBC) mode.

Solution

Upgrade the JBoss server to one of the patched versions listed in the vendor advisory, and enable galois/counter mode (GCM).
