Microsoft Windows Remote Desktop Gateway (RD Gateway) is a Windows Server component that provides access to Remote Desktop services without requiring the client system to be present on the same network as the target system. Originally launched as Terminal Services Gateway (TS Gateway) with Windows Server 2008, RD Gateway is a recommended way to provide Remote Desktop connectivity to cloud-based systems. For example, guidance has been provided for using RD Gateway with AWS, and also with Azure. The use of RD Gateway is recommended to reduce the attack surface of Windows-based hosts.Microsoft RD Gateway in Windows Server 2012 and later contain two vulnerabilities that can allow an unauthenticated remote malicious user to execute arbitrary code with SYSTEM privileges. It is reported by Kryptos Logic that the flaws lie in handling of fragmentation. This vulnerability is exploitable by connecting to the RD Gateway service listening on UDP/3391.
A remote code execution (RCE) exploit for Windows Remote Desktop Gateway (RD Gateway) was demoed by InfoGuard AG penetration tester Luca Marcelli, after a proof-of-concept denial of service exploit was released by Danish security researcher Ollypwn on Friday for the same pair of flaws.
The exploit targets the CVE-2020-0609 and CVE-2020-0610 bugs found in the Remote Desktop Gateway (RD Gateway) component on devices running Windows Server (2012, 2012 R2, 2016, and 2019).

Roundup Here comes a summary of this week's computer security news beyond what we've already covered.
An 18-year-old man from Canada has been accused of stealing more than $50m in cryptocurrency using SIM-swapping attacks.
SIM swapping typically involves crooks tricking cellular network support staff to transfer victims' smartphone numbers to the criminals' own SIMs, and then using those numbers to reset passwords, or get two-factor authentication tokens, via text messages, and ultim...
A proof-of-concept (PoC) denial of service exploit has been published by Danish security researcher Ollypwn for the CVE-2020-0609 and CVE-2020-0610 flaws affecting the Remote Desktop Gateway (RD Gateway) component on Windows Server (2012, 2012 R2, 2016, and 2019) devices.
RD Gateway is used to fence off Remote Desktop servers on internal networks from Internet connections and to only allow the ones that successfully authenticate on the gateway to reach the server.
