CVE-2020-28447Public exploitNetwork attack vector

Arbitrary command execution via unquoted filepath

Published Jul 25, 2022 · Updated Sep 17, 2024

OS command injection in Andrew Imm xopen 1.0.0 and earlier allows attackers to execute arbitrary commands through a crafted filepath. The exported xopen(filepath) function concatenates filepath after a platform-specific opener command and passes the unquoted string to child_process.exec. Exploitation requires a consuming Node.js application to pass attacker-controlled text into filepath; injected shell metacharacters then run with that application's privileges.
