CVE-2026-44724: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in sebhildebrandt systeminformation
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.
AI Analysis
Technical Summary
The systeminformation library for Node.js, used to gather system and OS information, contains an OS command injection vulnerability (CWE-78) in versions from 4.17.0 up to but not including 5.31.6 on Linux. The vulnerability occurs because the library sanitizes network interface names but fails to sanitize NetworkManager connection profile names before embedding them into shell commands executed with execSync(). This allows an attacker who can control or influence the connection profile name to inject arbitrary shell commands. The issue is resolved in version 5.31.6.
Potential Impact
Successful exploitation could lead to arbitrary code execution with the privileges of the Node.js process, potentially compromising confidentiality, integrity, and availability of the affected system. The CVSS v3.1 base score is 7.8 (high), reflecting local attack vector, low complexity, low privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade systeminformation to version 5.31.6 or later where this vulnerability is fixed. Since this is a library vulnerability, applying the official fix by updating the dependency is the recommended remediation. Patch status is confirmed fixed in 5.31.6. No other mitigations are indicated.
