FreeBSD : typo3 -- multiple vulnerabilities (eab964f8-d632-11ea-9172-4c72b94353b5)

Typo3 Team reports : In case an attacker manages to generate a valid cryptographic message authentication code HMAC-SHA1 - either by using a different existing vulnerability or in case the internal encryptionKey was exposed - it is possible to retrieve arbitrary files of a TYPO3 installation. Thi...

Remote Code Execution (RCE)

typo3/cms is vulnerable to insecure cryptography. During installation with mediace extension, the vulnerability exists because it was possible to generate arbitrary checksums that allows the injection of arbitrary data, allowing an attacker with at least one Extbase plugin or module action to...
