CVE-2024-52803Public exploitNetwork attack vector

Unauthenticated command execution via shell-enabled training launch

Published Nov 21, 2024 · Updated Nov 21, 2024

OS command injection in LlamaFactory before 0.9.1 allows remote attackers to execute arbitrary commands through its WebUI training workflow. The WebUI runner passes the user-controlled output_dir value into a formatted llamafactory-cli command and launches it with Popen shell=True. An unauthenticated request reaching the WebUI training interface is sufficient, and injected shell syntax runs with the server process's privileges.
