Descriptions

Local attackers can trigger a stack-based buffer overflow on vulnerable installations of Antiy-AVL ATool security management v1.0.0.22. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of IOCTL 0x80002000 by the IRPFile.sys Antiy-AVL ATool kernel driver. The bug is caused by failure to properly validate the length of the user-supplied data, which results in a kernel stack buffer overflow. An attacker can leverage this vulnerability to execute arbitrary code in the context of the kernel, which could lead to privilege escalation and a failed exploit could lead to denial of service.

Los atacantes locales pueden desencadenar un desbordamiento de búfer basado en pila en instalaciones vulnerables de la herramienta de gestión de seguridad Antiy-AVL ATool v1.0.0.22. En primer lugar, un atacante debe obtener la capacidad de ejecutar código de bajos privilegios en el sistema objetivo para explotar esta vulnerabilidad. Este error en concreto existe al procesar el IOCTL 0x80002000 por el controlador del kernel IRPFile.sys de Antiy-AVL ATool. El error proviene del error a la hora de validar correctamente la longitud de los datos proporcionados por el usuario, lo que resulta en un desbordamiento de búfer basado en la pila del kernel. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código arbitrario en el contexto del kernel, lo que podría conducir al escalado de privilegios; si la explotación falla, podría derivar en una denegación de servicio (DoS).
