Description

Systeminformation has a Command Injection via unsanitized interface parameter in wifi.js retry path

Summary

A command injection vulnerability in the wifiNetworks() function allows an attacker to execute arbitrary OS commands via an unsanitized network interface parameter in the retry code path.

Details

In lib/wifi.js, the wifiNetworks() function sanitizes the iface parameter on the initial call (line 437). However, when the initial scan returns empty results, a setTimeout retry (lines 440-441) calls getWifiNetworkListIw(iface) with the original unsanitized iface value, which is passed directly to execSync('iwlist ${iface} scan').

PoC

1. Install [email protected]

2. Call si.wifiNetworks('eth0; id')

3. The first call sanitizes input, but if results are empty, the retry executes: iwlist eth0; id scan

Impact

Remote Code Execution (RCE). Any application passing user-controlled input to si.wifiNetworks() is vulnerable to arbitrary command execution with the privileges of the Node.js process.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.

Weakness class

CVE-2026-26280 is classified as CWE-78: OS Command Injection. Untrusted input reaches a shell command without neutralisation, so an attacker can run arbitrary operating system commands.
