RDP Remote Code Execution Vulnerabilities

The threat

On August 13th, 2019, Microsoft announced multiple vulnerabilities in Remote Desktop Services (RDP) [1]. If exploited, an unauthenticated threat actor could execute remote code on vulnerable systems. CVE-2019-1181 and CVE-2019-1182 are rated critical due to the wide variety of vulnerable versions, while CVE-2019-1222 and CVE-2019-1226 affect fewer systems and remain unclassified. Attacks exploiting these vulnerabilities have not been identified in the wild at this time.

Due to the wide use of RDP and high value of Remote Code Execution (RCE), it is probable that exploitation will occur in the near future. Users and administrators should apply the latest Microsoft security patches as soon as possible.

Additional information

The major concern relating to CVE-2019-1181 and CVE-2019-1182 is wormability. If incorporated into existing malware types, the RDP vulnerabilities could be made to facilitate rapid malware spread. This risk may also be present in CVE-2019-1222 and CVE-2019-1226, but this remains unconfirmed at this time.

At the time of writing, Microsoft has disabled updates on machines running Symantec or Norton antivirus solutions, due to compatibility issues [2].
