Typo3 : Security Vulnerabilities, CVEs, (Code Execution) CVSS score >= 9

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. To successfully exploit this vulnerability, an attacker must have access to at least one `Extbase` plugin or module action in a TYPO3 installation. This is fixed in version 7.6.5 of the "mediace" extension for TYPO3.

TYPO3 8.x before 8.7.25 and 9.x before 9.5.6 allows remote code execution because it does not properly configure the applications used for image processing, as demonstrated by ImageMagick or GraphicsMagick.

Unspecified vulnerability in the Dictionary (rtgdictionary) extension 0.1.9 and earlier for TYPO3 allows attackers to execute arbitrary code via unknown vectors.

Unspecified vulnerability in the TYPO3 Secure Directory (kw_secdir) extension before 1.0.2 allows remote attackers to execute arbitrary code via unknown vectors related to "injection of control characters."
