In TYPO3 CMS greater than or equal to 9.0.0 and less than 9.5.20, and greater than or equal to 10.0.0 and less than 10.4.6, in a case where an attacker manages to generate a valid cryptographic message authentication code HMAC-SHA1 - either by using a different existing vulnerability or in case t...

CVE-2020-15099

CVE-2020-15099 affects TYPO3 CMS versions 9.0.0–9.5.19 and 10.0.0–10.4.5. An attacker who can construct a valid HMAC-SHA1 can access arbitrary files (e.g., typo3conf/LocalConfiguration.php) containing the encryptionKey and DB credentials, enabling full DB access and potentially creating an admin ...
