Overview
typo3/cms-core is a free open source enterprise content management system.
Affected versions of this package are vulnerable to Information Exposure. An internal verification mechanism can be used to generate arbitrary checksums. This allows to inject arbitrary data having a valid cryptographic message authentication code (HMAC-SHA1
) which can lead to a sensitive information disclosure.
Note: The attacker must have access to at least one Extbase plugin or module action in a TYPO3 installation.
