What is CVE-2024-55921?

TYPO3, a widely used open-source Content Management Framework, has a vulnerability in its backend user interface that is vulnerable to Cross-Site Request Forgery (CSRF). This flaw allows an attacker to initiate state-changing actions without proper authorization if they can persuade a user to click on a malicious link while logged in. This situation is exacerbated by misconfigurations such as disabling the security.backend.enforceReferrer feature or configuring BE/cookieSameSite settings improperly. Additionally, the vulnerability in the 'Extension Manager Module' permits attackers to inadvertently retrieve and install unauthorized third-party extensions from the TYPO3 Extension Repository, potentially leading to remote code execution. It is crucial for TYPO3 users to upgrade to the patched versions 11.5.42 ELTS, 12.4.25 LTS, or 13.4.3 LTS to mitigate this risk.
