Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

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.
