description-logoDescription

This indicates an attack against a remote Code Execution vulnerability in Microsoft .NET framework.
The vulnerability is caused by a lack of validation when the .NET Framework acquires the default web proxy settings and executes JavaScript within the proxy auto-configuration file. This vulnerability could allow remote code execution if an attacker on the network is able to convince the victim to use a malicious proxy auto configuration JavaScript file.
