CVE-2024-3126

Arbitrary command execution via unsanitized XTTS URL

Published May 16, 2024 · Updated Aug 1, 2024

OS command injection in ParisNeo LoLLMs WebUI before 9.5 allows attackers to execute arbitrary commands through xtts_base_url. The run_xtts_api_server function in lollms_xtts.py interpolates that input into a Python f-string and passes the resulting command to subprocess.Popen without neutralizing shell metacharacters. Reachability requires access to the application function and control of xtts_base_url; injected commands run with the server process's privileges.
