Microsoft released a security patch to address a Remote Code Execution(RCE) vulnerability that exists in its Remote Desktop Services (RDS). This vulnerability is rated critical and has a Common Vulnerability Scoring System (CVSS) score of 9.8.
An unauthenticated attacker could exploit this RCE flaw by sending a specially crafted request to systems running RDS via Remote Desktop Services (RDP), tricking it into executing the arbitrary code. This vulnerability is pre-authentication and requires no user interaction. The exploit code can also automatically replicate functional copies of themselves and cause widespread damage.
Successful exploitation of this vulnerability could allow attackers to take control of the affected system and perform malicious activities, including modifying and installing programs; view, change, or delete data; or create new accounts with full user rights.
