CVE-2026-44724: systeminformation: Linux command injection in networkInterfaces() via unsanitized NetworkManager connection profile name

systeminformation is a System and OS information library for node.js. From 4.17.0 to 5.31.5, on Linux, systeminformation is vulnerable to command injection in networkInterfaces() when an active NetworkManager connection profile name contains shell metacharacters. The vulnerable value is obtained internally from real nmcli device status output. The library sanitizes the network interface name before using it in shell commands, but it does not apply equivalent sanitization to the parsed NetworkManager connection profile name. That unsanitized connectionName is then interpolated into three shell command strings executed through execSync(). This vulnerability is fixed in 5.31.6.

Security readout for executives and security teams

Plain-English summary

A Node.js dependency can run unintended Linux shell commands if a local user can activate a specially named NetworkManager connection profile and the application calls networkInterfaces(). Impact is potentially full confidentiality, integrity, and availability loss on the affected host. The issue is fixed in systeminformation 5.31.6.

Executive priority

Treat as high priority where affected software runs on Linux with local user access. Patch dependency use promptly, but prioritize internet-facing services only if they also expose local code execution paths or shared-host access.

Technical view

CVE-2026-44724 is CWE-78 command injection in systeminformation versions 4.17.0 through 5.31.5 on Linux. networkInterfaces() parses nmcli device status, sanitizes interface names, but not the NetworkManager connection profile name before interpolating it into execSync() command strings.

Likely exposure

Exposure is most likely in Linux Node.js applications or bundled products using systeminformation and calling networkInterfaces(), especially where local users or administrators can create or activate NetworkManager profiles.

Exploitation context

The CVSS vector is local, low complexity, low privileges, and no user interaction. The provided sources do not show CISA KEV listing or active exploitation evidence, so active exploitation should not be claimed from this bundle.

Researcher notes

The vulnerable value is sourced internally from nmcli output, not directly from a network request. Validation should focus on dependency reachability, Linux runtime conditions, and whether attackers can influence active NetworkManager profile names.

Mitigation direction

  • Upgrade systeminformation to version 5.31.6 or later.
  • Check vendor advisories for downstream packages, including Red Hat guidance.
  • Restrict who can create or activate NetworkManager connection profiles.
  • Prioritize Linux hosts running applications that call networkInterfaces().
  • Review dependency lockfiles and rebuild affected applications after upgrading.

Validation and detection

  • Inventory applications and products that include systeminformation.
  • Confirm installed systeminformation versions are outside 4.17.0 through 5.31.5.
  • Identify Linux services that invoke networkInterfaces().
  • Review NetworkManager profile management permissions on affected hosts.
  • Check Red Hat errata applicability for managed distributions.
