CVE-2022-30190 has a CVSS score of 7.8/10, rated HIGH. Immediate patching is strongly recommended.

Which products are affected by CVE-2022-30190?

Affected package information for CVE-2022-30190 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2022-30190?

Apply the microsoft windows 7 security patch or hotfix for CVE-2022-30190 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2022-30190 across my infrastructure?

Inventory every microsoft windows 7 deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2022-30190 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2022-30190?

O3 detects and blocks CVE-2022-30190 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2022-30190 actively exploited in the wild?

Yes. There are 74 known exploit references for CVE-2022-30190, including 48 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2022-30190?

CVE-2022-30190 has an EPSS (Exploit Prediction Scoring System) score of 99.4%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2022-30190 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2022-30190 (Microsoft Windows Support Diagnostic Tool (MSDT) Remote Code Execution Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2022-06-14. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-07-05. The required action was: Apply updates per vendor instructions. This CVE has been used in known ransomware campaigns. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

Which products and versions are affected by CVE-2022-30190?

CVE-2022-30190 affects microsoft windows 7; microsoft windows 8.1; microsoft windows 10 20h2; microsoft windows 10 21h1, and 12 more product(s). Check the affected-products list on this page against your deployed version to confirm exposure.

Is there exploit tooling available for CVE-2022-30190?

2 Metasploit modules reference CVE-2022-30190, which lowers the barrier to weaponization. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2022-30190 published, and has it been updated?

CVE-2022-30190 was published on June 1, 2022 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

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.
