Arbitrary command execution via unsanitized shell input
Published Jan 8, 2021 · Updated Sep 17, 2024
Command injection in Radarsu ts-process-promises 1.0.2 allows context-dependent attackers to execute shell commands through the exec API. The exec function in lib/process-promises.js forwards its command string to Node.js child_process.exec, which invokes a platform shell without neutralizing metacharacters. Exploitation requires a consuming application to pass attacker-controlled text into that API, and resulting commands run with the application account's permissions.
