CVE-2020-1113

Se presenta una vulnerabilidad de omisión de la característica de seguridad en Microsoft Windows cuando el servicio Task Scheduler presenta un fallo al verificar apropiadamente las conexiones del cliente por medio de una RPC, también se conoce como "Windows Task Scheduler Security Feature Bypass Vulnerability".

Compass Security identified a security feature bypass vulnerability in Microsoft Windows. Due to the absence of integrity verification requirements for the RPC protocol and in particular the Task Scheduler, a man-in-the-middle attacker can relay his victim's NTLM authentication to a target of his choice over the RPC protocol. Provided the victim has administrative privileges on the target, the attacker can execute code on the remote target.
