Command execution via unsanitized wireless SSID
Published Dec 20, 2024 · Updated Dec 24, 2024
Command injection in systeminformation before 5.23.7 allows physically proximate attackers to execute commands through a malicious Wi-Fi SSID. getWindowsWirelessIfaceSSID reads the connected SSID from netsh output, and getWindowsIEEE8021x inserts it unescaped into a cmd.exe command. Exploitation requires a Windows host to connect to an attacker-controlled wireless network and invoke networkInterfaces(), after which commands run with the Node.js process's privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
