TYPO3 Mediacentric Extension Arbitrary Checksum Generate Remote Code Execution Vulnerability
Description
In TYPO3 installations with the "mediace" extension from version 7.6.2 and before version 7.6.5, it has been discovered that an internal verification mechanism can be used to generate arbitrary checksums. The allows to inject arbitrary data having a valid cryptographic message authentication code and can lead to remote code execution.
