A remote code execution vulnerability exists in Remote Desktop Services – formerly known as Terminal Services – when an unauthenticated attacker connects to the target system using RDP and sends specially crafted requests. This vulnerability is pre-authentication and requires no user interaction. An attacker who successfully exploited this vulnerability could execute arbitrary code on the target system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would need to send a specially crafted request to the target systems Remote Desktop Service via RDP.
The update addresses the vulnerability by correcting how Remote Desktop Services handles connection requests.

Detection & IOCsextracted from sources · hover to see the quote
- →Monitor for unauthenticated RDP connection attempts (pre-authentication exploitation) — no valid credentials will be presented before the malicious payload is sent. ↗
- →Alert on inbound RDP (TCP 3389) traffic from external/untrusted sources, especially where no Network Level Authentication (NLA) handshake is completed. ↗
- →Detect specially crafted RDP connection requests sent before authentication completes — look for anomalous or malformed RDP protocol sequences on TCP 3389. ↗
- ·Exploitation is rated 'More Likely' for both latest and older software releases by Microsoft, even though no public exploit or active exploitation was confirmed at time of disclosure. ↗
- ·Enabling NLA is a mitigating control but does NOT fully remediate the vulnerability — patching (KB4512501, KB4511553, KB4540673) is still required. ↗

[CRITICAL] August 2019 Patch Tuesday – 93 Vulns, 29 Critical, 7 Remote Desktop Vulns, Hyper-V, DHCP, Adobe vulns
Update Aug 13, 2019 : Detect and Patch Windows Remote Desktop Vulnerabilities
This month’s Microsoft Patch Tuesday addresses 93 vulnerabilities with 29 of them labeled as Critical. Of the 29 Critical vulns, 10 are for scripting engines and browsers, 6 for Windows Graphics/Font Library, and 4 are for Office apps. In addition, Microsoft has patched 4 (!) Critical RCEs in Remote Desktop (plus 3 Important), 2 for Hyper-V, 2 in DHCP Client/Server, and one for LNK files. Adobe has also released a large number of patches covering multiple products.
## Workstation Patches
Scripting Engine, Browser, Office, Graphics/Font, and LNK patches should be prioritized for workstation-type devices, meaning any system that is used for email or to access the internet via a browser. This includes multi-user
