Liferay Portal 6.1.0 Forward Target Handling Security Bypass

Critical Nessus Plugin ID 59359

Synopsis

The remote web server contains a Java application that is affected by a security bypass vulnerability.

Description

The version of Liferay Portal hosted on the remote web server contains a flaw in the 'PortletRequestDispatcherImpl' class's 'dispatch' method that allows a remote, unauthenticated attacker to create new administrative users. Since administrative users can install new plugins and extensions, this may lead to arbitrary code execution.

Note that this plugin only runs when the 'Perform thorough tests' setting is enabled and 'safe checks' are disabled.

Solution

Update to the newest version in Git or 6.2.0 when it becomes available.
