Description:
Several vulnerabilities were reported in TYPO3. A remote authenticated user can execute arbitrary code on the target system. A remote user can conduct cross-site scripting attacks. A remote authenticated user can obtain potentially sensitive information.
A remote authenticated user can exploit a flaw in 'view_help.php' to unserialize arbitrary objects and potentially execute arbitrary code on the target system. Felix Wilhelm reported this vulnerability.
A remote authenticated user can access the configuration module to obtain the Encryption Key. Mario Rimann reported this vulnerability.
The TYPO3 Backend, TYPO3 HTML Sanitizing API, and TYPO3 Install Tool do not properly filter HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the TYPO3 software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
Pavel Vaysband, Security Team Member Markus Bucher, Core Team Member Susanne Moog, and Jan Bednarik reported the backend vulnerabilities. Andreas Schnapp and Christian Nosterer reported the API vulnerability. Security Team Member Georg Ringer reported the TYPO3 Install Tool vulnerability.
