Source data

Overview

Use of uninitialized resource in Windows RDP allows an unauthorized attacker to execute code over a network.

Impact & technical details

Remote Code Execution

How could an attacker exploit this vulnerability? An attacker could exploit this vulnerability by sending specially crafted Remote Desktop Protocol (RDP) traffic to a system where Network Level Authentication (NLA) is disabled. The malicious data can interact with improperly initialized memory in the affected component, leading to memory corruption that the attacker may leverage to control how memory is written. This type of issue can allow an attacker to write data to unintended locations in memory, potentially enabling further compromise of the affected system.
