The Authentication component in TYPO3 before 6.2, when salting for password hashing is disabled, does not require knowledge of the cleartext password if the password hash is known, which allows remote attackers to bypass authentication and gain access to the backend by leveraging knowledge of a password hash.

The fileDenyPattern functionality in the PHP file inclusion protection API in TYPO3 4.2.x before 4.2.16, 4.3.x before 4.3.9, and 4.4.x before 4.4.5 does not properly filter file types, which allows remote attackers to bypass intended access restrictions and access arbitrary PHP files, as demonstrated using path traversal sequences with %00 null bytes and CVE-2010-3714 to read the TYPO3 encryption key from localconf.php.

Cross-site scripting (XSS) vulnerability in the FORM content object in TYPO3 4.2.x before 4.2.16, 4.3.x before 4.3.9, and 4.4.x before 4.4.5, allows remote authenticated users to inject arbitrary web script or HTML via unspecified vectors.

Directory traversal vulnerability in the TypoScript setup in TYPO3 4.2.x before 4.2.16, 4.3.x before 4.3.9, and 4.4.x before 4.4.5 allows remote authenticated administrators to read arbitrary files via unspecified vectors related to the "file inclusion functionality."

Directory traversal vulnerability in mod/tools/em/class.em_unzip.php in the unzip library in TYPO3 4.2.x before 4.2.16, 4.3.x before 4.3.9, and 4.4.x before 4.4.5 allows remote attackers to write arbitrary files via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in the Install Tool in TYPO3 4.2.x before 4.2.16, 4.3.x before 4.3.9, and 4.4.x before 4.4.5 allow remote authenticated users to inject arbitrary web script or HTML via unspecified vectors.

The escapeStrForLike method in TYPO3 4.2.x before 4.2.16, 4.3.x before 4.3.9, and 4.4.x before 4.4.5 does not properly escape input when the MySQL database is set to sql_mode NO_BACKSLASH_ESCAPES, which allows remote attackers to obtain sensitive information via wildcard characters in a LIKE query.

SQL injection vulnerability in the list module in TYPO3 4.2.x before 4.2.16, 4.3.x before 4.3.9, and 4.4.x before 4.4.5 allows remote authenticated users with certain permissions to execute arbitrary SQL commands via unspecified vectors.

The jumpUrl (aka access tracking) implementation in tslib/class.tslib_fe.php in TYPO3 4.2.x before 4.2.15, 4.3.x before 4.3.7, and 4.4.x before 4.4.4 does not properly compare certain hash values during access-control decisions, which allows remote attackers to read arbitrary files via unspecified vectors.

The be_user_creation task in TYPO3 4.2.x before 4.2.15 and 4.3.x before 4.3.7 allows remote authenticated users to gain privileges via a crafted POST request that creates a user account with arbitrary group memberships.
