Arbitrary command execution via interpolated process ID
Published Jun 1, 2022 · Updated Aug 4, 2024
OS command injection in allenhwkim proctree 0.1.1 and earlier allows attackers to execute arbitrary commands via a crafted process ID. The getProcessTree function interpolates its pid argument directly into a ps command passed to child_process.execSync without validation or shell-safe argument handling. Exploitation requires a consuming Node.js application to pass attacker-controlled input as the process ID, and successful injection executes with that application process's privileges.
