The $param variable from user input is interpolated into a command string within double quotes without sanitization via escapeshellarg(). The command is inserted into a database queue by safe_exec(), which performs no sanitization. The cycle_execs.php script, which is web-accessible without authentication, retrieves queued commands and passes them directly to exec(). An attacker can exploit a race condition by first triggering cycle_execs.php (which purges the queue and enters a polling loop), then injecting a malicious command via the rc endpoint while the worker is polling. The injected shell metacharacters expand inside double quotes, achieving remote code execution within one second."},{"lang":"es","value":"MajorDoMo (también conocido como Major Domestic Module) es vulnerable a la inyección de comandos del sistema operativo no autenticada a través de rc/index.php. La variable $param de la entrada del usuario se intercala en una cadena de comandos entre comillas dobles sin saneamiento a través de escapeshellarg(). El comando se inserta en una cola de la base de datos por safe_exec(), que no realiza ningún saneamiento. El script cycle_execs.php, que es accesible por la web sin autenticación, recupera los comandos en cola y los pasa directamente a exec(). Un atacante puede explotar una condición de carrera activando primero cycle_execs.php (que purga la cola y entra en un bucle de sondeo), luego inyectando un comando malicioso a través del punto final rc mientras el trabajador está sondeando.
