Descriptions

This vulnerability allows local attackers to execute arbitrary code on vulnerable installations of Bitdefender Total Security 21.0.24.62. 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 processing of the 0x8000E038 IOCTL in the bdfwfpf driver. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker could leverage this vulnerability to execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-4776.

Esta vulnerabilidad permite que los atacantes locales ejecuten código arbitrario en instalaciones vulnerables de Bitdefender Total Security 21.0.24.62. En primer lugar, un atacante debe obtener la habilidad para ejecutar código de bajos privilegios en el sistema objetivo para explotar esta vulnerabilidad. Este error en concreto existe al procesar el IOCTL 0x8000E038 en el controlador bdfwfpf. El problema deriva de la falta de validación de la existencia de un objeto previo a la realización de operaciones sobre el objeto. Un atacante podría aprovecharse de esta vulnerabilidad para ejecutar código arbitrario en el contexto de SYSTEM. Anteriormente era ZDI-CAN-4776.
