Microsoft Support Diagnostic Tool Vulnerability CVE-2022-30190

• Windows Office Product Spawning MSDT :
  endpoint Endpoint risk_score:100 2024-11-28 version:8
  The following analytic detects a Microsoft Office product spawning the Windows msdt.exe process. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process creation events where Office applications are the parent process. This activity is significant as it may indicate an attempt to exploit protocol handlers to bypass security controls, even if macros are disabled. If confirmed malicious, this behavior could allow an attacker to execute arbitrary code, potentially leading to system compromise, data exfiltration, or further lateral movement within the network.


• Windows Command and Scripting Interpreter Path Traversal Exec :
  endpoint Endpoint risk_score:90 2024-11-28 version:5
  The following analytic detects path traversal command-line execution, often used in malicious documents to execute code via msdt.exe for defense evasion. It leverages Endpoint Detection and Response (EDR) data, focusing on specific patterns in process paths. This activity is significant as it can indicate an attempt to bypass security controls and execute unauthorized code. If confirmed malicious, this behavior could lead to code execution, privilege escalation, or persistence within the environment, potentially allowing attackers to deploy malware or leverage other living-off-the-land binaries (LOLBins).


• Windows Command and Scripting Interpreter Hunting Path Traversal :
  endpoint Endpoint risk_score:36 2024-10-17 version:3
  The following analytic identifies path traversal command-line executions, leveraging data from Endpoint Detection and Response (EDR) agents. It detects patterns in command-line arguments indicative of path traversal techniques, such as multiple instances of "/..", "\..", or "\\..". This activity is significant as it often indicates attempts to evade defenses by executing malicious code, such as through msdt.exe. If confirmed malicious, this behavior could allow attackers to execute arbitrary code, potentially leading to system compromise, data exfiltration, or further lateral movement within the network.


• Windows Execute Arbitrary Commands with MSDT :
  endpoint Endpoint risk_score:100 2024-11-28 version:7
  The following analytic detects arbitrary command execution using Windows msdt.exe, a Diagnostics Troubleshooting Wizard. It leverages Endpoint Detection and Response (EDR) data to identify instances where msdt.exe is invoked via the ms-msdt:/ protocol handler to retrieve a remote payload. This activity is significant as it can indicate an exploitation attempt leveraging msdt.exe to execute arbitrary commands, potentially leading to unauthorized code execution. If confirmed malicious, this could allow an attacker to execute arbitrary code, escalate privileges, or persist within the environment, posing a severe security risk.
