Description
In MISP, the __statisticsOrgs method in UsersController.php used the organization name directly as a file-system path component when checking for the existence of an organization logo image. The original code called file_exists() with a path constructed as APP . 'webroot' . DS . 'img' . DS . 'orgs' . DS . $k . '.png', where $k is the organization name. Because the referenced directory (app/webroot/img/orgs) no longer exists in current MISP deployments (org logos were relocated to files/img/orgs), the check was functionally dead and never triggered. However, the underlying pattern—concatenating an attacker-influenced organization name into a file path without sanitization—constitutes a path traversal weakness. An organization name containing directory traversal sequences (e.g., '../../../../etc/passwd') would, if the target directory existed, allow an authenticated user with the ability to create or rename an organization to probe for the existence of arbitrary files on the server.
