Release Date: September 26, 2014
Component Type: Third party extension. This extension is not a part of the TYPO3 default installation.
Affected Versions: version 4.18.2 and below
Vulnerability Type: XSS, CSRF
Problem Description: With several usage actions it is possible to trigger XSS in various components. By deceiving a logged-in user to click on a crafted URL, it is possible to perform remote code execution and in some cases, create a root account due to a DOM based XSS vulnerability in the micro history feature.
Solution: An updated version 4.18.3 is available from the TYPO3 extension manager and at http://typo3.org/extensions/repository/download/phpmyadmin/4.18.3/t3x/. Users of the extension are advised to update the extension as soon as possible.
