Microsoft Windows IIS Remote Code Execution Vulnerability

A remote code execution vulnerability exists when Microsoft Windows fails to properly validate input before loading certain libraries. An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

To exploit the vulnerability, an attacker must first gain access to the local system and have the ability to execute a malicious application. The security update addresses the vulnerability by correcting how Windows validates input when loading certain libraries.
