CVE-2023-37754Public exploitNetwork attack vector

Unauthenticated command execution via built-in script processors

Published Jul 28, 2023 · Updated Oct 23, 2024

Remote command execution in PowerJob 4.3.3 allows remote attackers to run operating-system commands through built-in script processors. AbstractScriptProcessor writes console-supplied job content to a generated script, and ProcessBuilder invokes it with the selected processor. Network access and a connected worker with the relevant processor suffice because the server APIs lack authentication; the CVE record separately names instanceId at /instance/detail without showing that data flow.
