Cross-site scripting (XSS) vulnerability in the file backend module in TYPO3 4.2.2 allows remote attackers to inject arbitrary web script or HTML via unknown vectors.

Cross-site scripting (XSS) vulnerability in fe_adminlib.inc in TYPO3 4.0.x before 4.0.9, 4.1.x before 4.1.7, and 4.2.x before 4.2.1, as used in extensions such as (1) direct_mail_subscription, (2) feuser_admin, and (3) kb_md5fepw, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

TYPO3 4.0.x before 4.0.9, 4.1.x before 4.1.7, and 4.2.x before 4.2.1, uses an insufficiently restrictive default fileDenyPattern for Apache, which allows remote attackers to bypass security restrictions and upload configuration files such as .htaccess, or conduct file upload attacks using multiple extensions.

SQL injection vulnerability in the indexed_search system extension in TYPO3 3.x, 4.0 through 4.0.7, and 4.1 through 4.1.3 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors.

MySQLDumper 1.21b through 1.23 REV227 uses a "Limit GET" statement in the .htaccess authentication mechanism, which allows remote attackers to bypass authentication requirements via HTTP POST requests.

The start function in class.t3lib_formmail.php in TYPO3 before 4.0.5, 4.1beta, and 4.1RC1 allows attackers to inject arbitrary email headers via unknown vectors. NOTE: some details were obtained from third party information.

rtehtmlarea/pi1/class.tx_rtehtmlarea_pi1.php in Typo3 4.0.0 through 4.0.3, 3.7 and 3.8 with the rtehtmlarea extension, and 4.1 beta allows remote authenticated users to execute arbitrary commands via shell metacharacters in the userUid parameter to rtehtmlarea/htmlarea/plugins/SpellChecker/spell-check-logic.php, and possibly another vector.

Cross-site scripting (XSS) vulnerability in class.tx_indexedsearch.php in the Indexed Search 2.9.0 extension for Typo3 before 4.0.2 and earlier allows remote attackers to inject arbitrary web script or HTML via the search parameter.

TYPO3 3.7.1 allows remote attackers to obtain sensitive information via a direct request to (1) thumbs.php, (2) showpic.php, or (3) tables.php, which causes them to incorrectly define a variable and reveal the path in an error message when a require function call fails.

TYPO3 3.8.0 and earlier allows remote attackers to obtain sensitive information via a direct request to misc/phpcheck/, which invokes the phpinfo function and prints values of unspecified environment variables.
