Résumé
WWBN AVideo has a Path Traversal in Locale Save Endpoint that Enables Arbitrary PHP File Write to Any Web-Accessible Directory (RCE)
Description d'origine
La description telle que publiée par la source (souvent en anglais).
WWBN AVideo is an open source video platform. In versions 29.0 and prior, the locale save endpoint (locale/save.php) constructs a file path by directly concatenating $_POST['flag'] into the path at line 30 without any sanitization. The $_POST['code'] parameter is then written verbatim to that path via fwrite() at line 40. An admin attacker (or any user who can CSRF an admin, since no CSRF token is checked and cookies use SameSite=None) can traverse out of the locale/ directory and write arbitrary .php files to any writable location on the filesystem, achieving Remote Code Execution. Commit 57f89ffbc27d37c9d9dd727212334846e78ac21a fixes the issue.
