Arbitrary command execution via unquoted psargs
Published Feb 8, 2021 · Updated Sep 16, 2024
OS command injection in Fortruce node-ps 0.0.2 and earlier allows attackers to execute arbitrary commands through crafted psargs. The lookup function passes query.psargs to _ps, which joins the array into an unquoted shell command and invokes child_process.exec. Exploitation requires a consuming application to place attacker-controlled strings in psargs; injected commands run with the Node.js process privileges.
