Open redirect vulnerability in the Access tracking mechanism in TYPO3 4.5.x before 4.5.24, 4.6.x before 4.6.17, 4.7.x before 4.7.9, and 6.0.x before 6.0.3 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors.

view_help.php in the backend help system in TYPO3 4.5.x before 4.5.19, 4.6.x before 4.6.12 and 4.7.x before 4.7.4 allows remote authenticated backend users to unserialize arbitrary objects and possibly execute arbitrary PHP code via an unspecified parameter, related to a "missing signature (HMAC)."

The Command Line Interface (CLI) script in TYPO3 4.4.0 through 4.4.13, 4.5.0 through 4.5.13, 4.6.0 through 4.6.6, 4.7, and 6.0 allows remote attackers to obtain the database name via a direct request.

The t3lib_div::RemoveXSS API method in TYPO3 4.4.0 through 4.4.13, 4.5.0 through 4.5.13, 4.6.0 through 4.6.6, 4.7, and 6.0 allows remote attackers to bypass the cross-site scripting (XSS) protection mechanism and inject arbitrary web script or HTML via non printable characters.

Multiple cross-site scripting (XSS) vulnerabilities in the Backend component in TYPO3 4.4.0 through 4.4.13, 4.5.0 through 4.5.13, 4.6.0 through 4.6.6, 4.7, and 6.0 allow remote authenticated backend users to inject arbitrary web script or HTML via unspecified vectors.

The Extbase Framework in TYPO3 4.6.x through 4.6.6, 4.7, and 6.0 unserializes untrusted data, which allows remote attackers to unserialize arbitrary objects and possibly execute arbitrary code via vectors related to "a missing signature (HMAC) for a request argument."
