Descriptions

Code injection vulnerability in Bitdefender Total Security 12.0 (and earlier), Internet Security 12.0 (and earlier), and Antivirus Plus 12.0 (and earlier) allows a local attacker to bypass a self-protection mechanism, inject arbitrary code, and take full control of any Bitdefender process via a "DoubleAgent" attack. One perspective on this issue is that (1) these products do not use the Protected Processes feature, and therefore an attacker can enter an arbitrary Application Verifier Provider DLL under Image File Execution Options in the registry; (2) the self-protection mechanism is intended to block all local processes (regardless of privileges) from modifying Image File Execution Options for these products; and (3) this mechanism can be bypassed by an attacker who temporarily renames Image File Execution Options during the attack.

Vulnerabilidad de inyección de código en Bitdefender Total Security 12.0 (y versiones anteriores), Internet Security 12.0 (y versiones anteriores) y Antivirus Plus 12.0 (y versiones anteriores) permite a un atacante local evitar un mecanismo de autoprotección, inyectar código arbitrario, y tomar el control total de cualquier proceso Bitdefender a través de un ataque "DoubleAgent". Una perspectiva de este problema es que (1) estos productos no utilizan la característica de procesos protegidos y, por lo tanto, un atacante puede introducir un proveedor verificador de aplicaciones DLL arbitrario bajo opciones de ejecución de archivo de imagen en el registro; (2) el mecanismo de autoprotección está destinado a bloquear todos los procesos locales (independientemente de los privilegios) de modificar las opciones de ejecución de archivos de imagen para estos productos; y (3) este mecanismo puede ser anulado por un atacante que cambia temporalmente las opciones de ejecución de archivo de imagen durante el ataque.
