Discussion
TYPO3 Backend File Upload / File Abstraction Layer Extension Arbitrary File Upload Vulnerability
The Backend File Upload / File Abstraction Layer extension for TYPO3 is prone to a vulnerability that lets attackers upload arbitrary files. The issue occurs because the application fails to adequately validate user-supplied input.
An attacker can exploit this vulnerability to upload arbitrary code and execute it in the context of the Web server process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible.
Backend File Upload / File Abstraction Layer versions 6.0.0 through versions 6.2 are vulnerable.
