What is CVE-2020-26228?

TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 9.5.23 and 10.4.10 user session identifiers were stored in cleartext - without processing with additional cryptographic hashing algorithms. This vulnerability cannot be exploited directly and occurs in combination with a chained attack - like for instance SQL injection in any other component of the system. Update to TYPO3 versions 9.5.23 or 10.4.10 that fix the problem described.

Affected Version(s)

TYPO3.CMS >= 9.0.0, < 9.5.23 < 9.0.0, 9.5.23

TYPO3.CMS >= 10.0.0, < 10.4.10 < 10.0.0, 10.4.10
