The Authentication component in TYPO3 6.2.0 before 6.2.3 does not properly invalidate timed out user sessions, which allows remote attackers to bypass authentication via unspecified vectors.

TYPO3 4.5.0 before 4.5.34, 4.7.0 before 4.7.19, 6.0.0 before 6.0.14, 6.1.0 before 6.1.9, and 6.2.0 before 6.2.3 allows remote attackers to have unspecified impact via a crafted HTTP Host header, related to "Host Spoofing."

Multiple cross-site scripting (XSS) vulnerabilities in unspecified backend components in TYPO3 4.5.0 before 4.5.34, 4.7.0 before 4.7.19, 6.0.0 before 6.0.14, 6.1.0 before 6.1.9, and 6.2.0 before 6.2.3 allow remote authenticated editors to inject arbitrary web script or HTML via unknown parameters.

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 query caching functionality in the Extbase Framework component in TYPO3 6.2.0 before 6.2.3 does not properly validate group permissions, which allows remote authenticated users to read arbitrary queries via unspecified vectors.

The Color Picker Wizard component in TYPO3 4.5.0 before 4.5.34, 4.7.0 before 4.7.19, 6.0.0 before 6.0.14, and 6.1.0 before 6.1.9 allows remote authenticated editors to execute arbitrary PHP code via a serialized PHP object.

The File Abstraction Layer (FAL) in TYPO3 6.0.x before 6.0.8 and 6.1.x before 6.1.4 allows remote authenticated editors to execute arbitrary PHP code via unspecified characters in the file extension when renaming a file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-4250.

The Backend History Module in TYPO3 4.5.x before 4.5.21, 4.6.x before 4.6.14, and 4.7.x before 4.7.6 does not properly restrict access, which allows remote authenticated editors to read the history of arbitrary records via a crafted URL.

The File Abstraction Layer (FAL) in TYPO3 6.0.x before 6.0.9 and 6.1.x before 6.1.4 does not properly check permissions, which allows remote authenticated users to create or read arbitrary files via a crafted URL.

The (1) file upload component and (2) File Abstraction Layer (FAL) in TYPO3 6.0.x before 6.0.8 and 6.1.x before 6.1.3 do not properly check file extensions, which allow remote authenticated editors to execute arbitrary PHP code by uploading a .php file.
