CVE-2022-30190: Microsoft Windows Support Diagnostic Tool (MSDT) Remote Code Execution Vulnerability

Noroxi assessment

Priority: Now (action score 91/100)

  • CISA has confirmed exploitation in the wild (Jun 14, 2022); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Jul 5, 2022.
  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 99.1% (FIRST EPSS); higher than 99.9% of all records.
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Mentioned 5 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

A remote code execution vulnerability exists when MSDT is called using the URL protocol from a calling application such as Word. An attacker who successfully exploits this vulnerability can run arbitrary code with the privileges of the calling application. The attacker can then install programs, view, change, or delete data, or create new accounts in the context allowed by the user’s rights. Please see the MSRC Blog Entry for important information about steps you can take to protect your system from this vulnerability.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Jun 14, 2022. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Jul 5, 2022.

Known to be used in ransomware campaigns.
