Several remote vulnerabilities have been discovered in the TYPO3 web content management framework: cross-site Scripting, open redirection, SQL injection, broken authentication and session management, insecure randomness, information disclosure and arbitrary code execution. More details can be found in the Typo3 security advisory: http://typo3.org/teams/security/security-bulletins/typo3-sa-2010-012/ For the stable distribution (lenny), these problems have been fixed in version 4.2.5-1+lenny4.
