The service requires root privileges for certain administrative operations, but these checks rely on calls to geteuid(). By preloading a malicious shared object overriding geteuid(), a local attacker can trick the service into believing it is running with root privileges. This bypass enables execution of administrative commands (e.g., enabling debug mode, managing configurations, or invoking privileged features) without proper authorization. While some actions requiring write access to protected files may still fail, the flaw effectively breaks the intended security model of the inter-process communication (IPC) system, allowing local attackers to escalate privileges and compromise system integrity.\u00a0This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced."}, {"lang": "es", "value": "Las versiones de Vasion Print (anteriormente PrinterLogic) Virtual Appliance Host anteriores a la 25.1.102 y las versiones de aplicaci\u00f3n anteriores a la 25.1.1413 (implementaciones de cliente macOS/Linux) son vulnerables a una omisi\u00f3n de autenticaci\u00f3n en PrinterInstallerClientService. El servicio requiere privilegios de root para ciertas operaciones administrativas, pero estas comprobaciones se basan en llamadas a geteuid(). Al precargar un objeto compartido malicioso que anula geteuid(), un atacante local puede enga\u00f1ar al servicio para que crea que se est\u00e1 ejecutando con privilegios de root. Esta omisi\u00f3n permite la ejecuci\u00f3n de comandos administrativos (por ejemplo, habilitar el modo de depuraci\u00f3n, gestionar configuraciones o invocar funciones privilegiadas) sin la autorizaci\u00f3n adecuada. Si bien algunas acciones que requieren acceso de escritura a archivos protegidos a\u00fan pueden fallar, la falla rompe efectivamente el modelo de seguridad previsto del sistema de comunicaci\u00f3n entre procesos (IPC), permitiendo a los atacantes locales escalar privilegios y comprometer la integridad del sistema.
