Liferay Portal 6.1.0 'addUser()' Security Bypass

critical Nessus Plugin ID 59232

Synopsis

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

Description

The version of Liferay Portal hosted on the remote web server contains a flaw in the 'UserServiceUtil' class's 'addUser' 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.

In addition, this version of Liferay Portal may be affected by a reconfiguration vulnerability that may allow the backing store to be switched to an arbitrary, attacker-controlled server. However, Nessus has not tested for this.

Solution

Update to a version after 6.1.0 or use the newest version in SVN.
