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.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
