CVE-2024-3126

Command injection in 'run_xtts_api_server' allows remote code execution.

• CVSS 8.4
• CWE-78
• Input Validation and Sanitization
• Remote

A command injection vulnerability exists in the 'run_xtts_api_server' function of the parisneo/lollms-webui application, specifically within the 'lollms_xtts.py' script. The vulnerability arises due to the improper neutralization of special elements used in an OS command. The affected function utilizes 'subprocess.Popen' to execute a command constructed with a Python f-string, without adequately sanitizing the 'xtts_base_url' input. This flaw allows attackers to execute arbitrary commands remotely by manipulating the 'xtts_base_url' parameter. The vulnerability affects versions up to and including the latest version before 9.5. Successful exploitation could lead to arbitrary remote code execution (RCE) on the system where the application is deployed.
