Remote OS Command Execution Vulnerability in rejetto HFS (aka HTTP File Server) 3 before 0.52.10 on Linux, UNIX, and macOS

CVE-2024-39943

Summary

The vulnerability CVE-2024-39943 affects the rejetto HFS (HTTP File Server) 3 before 0.52.10 on Linux, UNIX, and macOS, allowing remote authenticated users with upload permissions to execute OS commands through the use of execSync instead of spawnSync in the child_process module of Node.js. Exploitation of this vulnerability can lead to attackers gaining control over vulnerable systems, potentially resulting in significant security breaches such as data theft and system compromise. Users are strongly advised to update to version 0.52.10 or later to mitigate this vulnerability, and in the meantime, temporarily disabling upload permissions for all users and implementing strong authentication mechanisms can help reduce the risk of exploitation. Regular audits and updates to the system are also recommended to maintain security.
