It fails to properly authenticate clients over the XPC protocol and does not correctly enforce macOS\u2019s authorization model, exposing privileged functionality to untrusted users. Although it invokes the AuthorizationCopyRights API, it does so using overly permissive custom rights that it registers in the system\u2019s authorization database (/var/db/auth.db).\n\n\nThese rights can be requested and granted by the authorization daemon to any local user, regardless of privilege level. As a result, an attacker can exploit the vulnerable service to perform privileged operations such as executing arbitrary commands or installing system components without requiring administrative credentials."}, {"lang": "es", "value": "La herramienta com.epson.InstallNavi.helper, desplegada con el instalador del controlador de impresora EPSON, contiene una vulnerabilidad de escalada de privilegios local debido a m\u00faltiples fallos en su implementaci\u00f3n.
