0 ConcreteCMS version 9.4.7 contains a Denial of Service (DoS) vulnerability in its File Manager component. The vulnerability arises from the 'download' method in 'concrete/controllers/backend/file.php', which improperly handles memory when creating zip archives by loading entire file contents into PHP memory. An authenticated attacker can exploit this by requesting bulk downloads of large files, causing an Out-Of-Memory (OOM) condition that crashes the PHP-FPM process and results in HTTP 500 errors. This vulnerability does not affect confidentiality or integrity but severely impacts availability. Exploitation requires authentication but no user interaction beyond sending the request. There are no known exploits in the wild currently, and no patches have been linked yet. The CVSS score is 6.
