Typo Security Team reports :

It has been discovered that TYPO3 Core is vulnerable to Cross-Site Scripting, Information Disclosure, Insecure Unserialize leading to Arbitrary Code Execution.

TYPO3 Backend Help System - Due to a missing signature (HMAC) for a parameter in the view_help.php file, an attacker could unserialize arbitrary objects within TYPO3. We are aware of a working exploit, which can lead to arbitrary code execution. A valid backend user login or multiple successful cross site request forgery attacks are required to exploit this vulnerability.

TYPO3 Backend - Failing to properly HTML-encode user input in several places, the TYPO3 backend is susceptible to Cross-Site Scripting. A valid backend user is required to exploit these vulnerabilities.

TYPO3 Backend - Accessing the configuration module discloses the Encryption Key. A valid backend user with access to the configuration module is required to exploit this vulnerability.

TYPO3 HTML Sanitizing API - By not removing several HTML5 JavaScript events, the API method t3lib_div::RemoveXSS() fails to filter specially crafted HTML injections, thus is susceptible to Cross-Site Scripting. Failing to properly encode for JavaScript the API method t3lib_div::quoteJSvalue(), it is susceptible to Cross-Site Scripting.

TYPO3 Install Tool - Failing to properly sanitize user input, the Install Tool is susceptible to Cross-Site Scripting.


Update the affected packages.
