FileProcessorService validates the raw filename but FileManager::sanitizeFileName() strips the space, storing an executable .php file under public/cache/documents/ for code execution as the web server user.","cvssScore":7.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-434"],"vendors":[],"products":[],"references":[{"url":"https://github.com/thelia/thelia/blob/3.2.0/core/lib/Thelia/Core/File/Service/FileProcessorService.php#L119-L160","tags":[]},{"url":"https://github.com/thelia/thelia/commit/6b706f5cb96e6b12d890c6d16edb1c9d1fd8191a","tags":[]},{"url":"https://github.com/thelia/thelia/commit/b71258902b5dd278007d0f37ddad45f76d06d5bc","tags":[]},{"url":"https://github.com/thelia/thelia/releases/tag/3.1.2","tags":[]},{"url":"https://github.com/thelia/thelia/releases/tag/3.2.1","tags":[]},{"url":"https://github.com/thelia/thelia/security/advisories/GHSA-5524-qfxp-33v9","tags":[]},{"url":"https://www.vulncheck.com/advisories/thelia-before-3.1.2-and-3.2-x-before-3.2.1-file-upload-rce-via-filename-trailing-space","tags":[]}],"exploitRefs":[{"url":"https://github.com/thelia/thelia/blob/3.2.0/core/lib/Thelia/Core/File/Service/FileProcessorService.php#L119-L160","tags":[]},{"url":"https://github.com/thelia/thelia/commit/6b706f5cb96e6b12d890c6d16edb1c9d1fd8191a","tags":[]},{"url":"https://github.com/thelia/thelia/commit/b71258902b5dd278007d0f37ddad45f76d06d5bc","tags":[]},{"url":"https://github.com/thelia/thelia/releases/tag/3.1.2","tags":[]},{"url":"https://github.com/thelia/thelia/releases/tag/3.2.1","tags":[]},{"url":"https://github.com/thelia/thelia/security/advisories/GHSA-5524-qfxp-33v9","tags":[]}],"hasPoc":true,"ai":null}
