TYPO3 is an open source PHP based web content management system released under the GNU GPL. In affected versions of TYPO3 entities of the File Abstraction Layer (FAL) could be persisted directly via DataHandler. This allowed attackers to reference files in the fallback storage directly and retrieve their file names and contents. The fallback storage ("zero-storage") is used as a backward compatibility layer for files located outside properly configured file storages and within the public web root directory. Exploiting this vulnerability requires a valid backend user account. Users are advised to update to TYPO3 version 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, or 13.0.1 which fix the problem described. When persisting entities of the File Abstraction Layer directly via DataHandler, sys_file entities are now denied by default, and sys_file_reference & sys_file_metadata entities are not permitted to reference files in the fallback storage anymore. When importing data from secure origins, this must be explicitly enabled in the corresponding DataHandler instance by using $dataHandler->isImporting = true;.
CVE-2024-25121
This high-severity CVE scores 7.1 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 60% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
