Description

Several vulnerabilities were discovered in TYPO3, a content management system.

  • CVE-2012-3527 An insecure call to unserialize in the help system enables arbitrary code execution by authenticated users.

  • CVE-2012-3528 The TYPO3 backend contains several cross-site scripting vulnerabilities.

  • CVE-2012-3529 Authenticated users who can access the configuration module can obtain the encryption key, allowing them to escalate their privileges.

  • CVE-2012-3530 The RemoveXSS HTML sanitizer did not remove several HTML5 JavaScript, thus failing to mitigate the impact of cross-site scripting vulnerabilities.
