CVE-2018-1161

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Quest NetVault Backup 11.2.0.13. Authentication is not required to exploit this vulnerability. The specific flaw exists within nvwsworker.exe. When parsing the boundary header of a multipart request, the process does not properly validate the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of SYSTEM. Was ZDI-CAN-4215.

Esta vulnerabilidad permite que los atacantes remotos ejecuten código arbitrario en instalaciones vulnerables de Quest NetVault Backup 11.2.0.13. No se requiere autenticación para explotar esta vulnerabilidad. Este error en concreto existe en nvwsworker.exe. Al analizar la cabecera de límite de una petición de varias partes, el proceso no valida adecuadamente la longitud de los datos proporcionados por el usuario antes de copiarlos en un búfer basado en pila. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del sistema. Anteriormente era ZDI-CAN-4215.
