ajorDoMo (aka Major Domestic Module) contains an unauthenticated SQL injection vulnerability in the commands module. The commands_search.inc.php file directly interpolates the $_GET['parent'] parameter into multiple SQL queries without sanitization or parameterized queries. The commands module is loadable without authentication via the /objects/?module=commands endpoint, which includes arbitrary modules by name and calls their usual() method. Time-based blind SQL injection is exploitable using UNION SELECT SLEEP() syntax. Because MajorDoMo stores admin passwords as unsalted MD5 hashes in the users table, successful exploitation enables extraction of credentials and subsequent admin panel access.

Summary
  • (es) MajorDoMo (también conocido como Major Domestic Module) contiene una vulnerabilidad de inyección SQL no autenticada en el módulo de comandos. El archivo commands_search.inc.php interpola directamente el parámetro $_GET['parent'] en múltiples consultas SQL sin saneamiento o consultas parametrizadas. Se puede cargar el módulo de comandos sin autenticación a través del endpoint /objects/?module=commands, que incluye módulos arbitrarios por nombre y llama a su método usual(). Es posible explotar la inyección SQL ciega basada en tiempo usando la sintaxis UNION SELECT SLEEP(). Debido a que MajorDoMo almacena las contraseñas de administrador como hashes MD5 sin sal en la tabla de usuarios, en caso de que se eplote con éxito se puede extraer credenciales y, posteriormente, acceder al panel de administración.
