CVE-2024-56334

CVE-2024-56334: Systeminformation has command injection vulnerability in getWindowsIEEE8021x (SSID)

Summary

The SSID is not sanitized when before it is 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.

Details

I have exploited this vulnerability in a Windows service using version 5.22.11 of the module, to escalate privileges (in an environment where I am authorized to do so). However, as far as I can see from the code, it is still present in master branch at time of writing, on line 403/404 of network.js.

The SSID is obtained from netsh wlan show interface ... in getWindowsWirelessIfaceSSID, and then passed to cmd.exe /d /s /c "netsh wlan show profiles ... in getWindowsIEEE8021x, without sanitization.

PoC

First, the command injection payload should be included in the connected Wi-Fi SSID. For example create hotspot on mobile phone or other laptop, set SSID to payload, connect to it with victim Windows system. Two example SSID's to demonstrate exploitation are below.

Demonstration to run ping command indefinitely:

a" | ping /t 127.0.0.1 &

Run executable with privileges of the user in which vulnerable function is executed. Chosen executable should should be placed in (assuming system drive is C): C:\a\a.exe.

a" | %SystemDrive%\a\a.exe &

Then, the vulnerable function can be executed on the victim system, for example, using:

const si = require('systeminformation');
si.networkInterfaces((net) => { console.log(net) });

Now the chosen command, PING.exe or a.exe will be run through the cmd.exe command line.

Impact

This vulnerability may enable an attacker, depending on how the package is used, to perform remote code execution or local privilege escalation.

Root Cause Analysis

The primary vulnerability occurs in getWindowsIEEE8021x where unsanitized SSID values from getWindowsWirelessIfaceSSID are directly interpolated into execSync commands. The commit diff shows added sanitization in both functions - trimming in getWindowsWirelessIfaceSSID and full sanitization in getWindowsIEEE8021x. While the injection occurs in getWindowsIEEE8021x, getWindowsWirelessIfaceSSID's role in supplying untrusted input makes it indirectly vulnerable. Confidence is high for getWindowsIEEE8021x as the injection point, and medium for getWindowsWirelessIfaceSSID as an enabler.
