How severe is CVE-2024-56334?

CVE-2024-56334 has a CVSS score of 7.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2024-56334?

CVE-2024-56334 affects the following packages: systeminformation (npm). Ecosystems affected: npm.

How do I fix CVE-2024-56334?

Update systeminformation to 5.23.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-56334 is resolved across your whole dependency graph.

How do I detect CVE-2024-56334 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for systeminformation. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2024-56334 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2024-56334?

O3 pinpoints whether CVE-2024-56334 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2024-56334 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-56334 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-56334?

CVE-2024-56334 has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 48th 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. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was CVE-2024-56334 published, and has it been updated?

CVE-2024-56334 was published on December 20, 2024 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

systeminformation is a System and OS information library for node.js. In affected versions SSIDs are not sanitized when before they are passed as a parameter to cmd.exe in the getWindowsIEEE8021x function. This means that malicious content in the SSID can be executed as OS commands. This vulnerability may enable an attacker, depending on how the package is used, to perform remote code execution or local privilege escalation. This issue has been addressed in version 5.23.7 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
