CVE-2023-42810 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by CVE-2023-42810?

CVE-2023-42810 affects the following packages: systeminformation (npm). Ecosystems affected: npm.

How do I fix CVE-2023-42810?

Update systeminformation to 5.21.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-42810 is resolved across your whole dependency graph.

How do I detect CVE-2023-42810 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-2023-42810 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-2023-42810?

O3 pinpoints whether CVE-2023-42810 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-2023-42810 actively exploited in the wild?

No public exploit code has been indexed for CVE-2023-42810 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-2023-42810?

CVE-2023-42810 has an EPSS (Exploit Prediction Scoring System) score of 1.8%, placing it in the 76th 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.

What type of vulnerability is CVE-2023-42810?

CVE-2023-42810 is classified as CWE-77 (CWE-77). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2023-42810 published, and has it been updated?

CVE-2023-42810 was published on September 21, 2023 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 Information Library for Node.JS. Versions 5.0.0 through 5.21.6 have a SSID Command Injection Vulnerability. The problem was fixed with a parameter check in version 5.21.7. As a workaround, check or sanitize parameter strings that are passed to wifiConnections(), wifiNetworks() (string only).
