rejetto HFS vulnerable to OS Command Execution by remote authenticated users

Description

rejetto HFS (aka HTTP File Server) 3 before 0.52.10 on Linux, UNIX, and macOS allows OS command execution by remote authenticated users (if they have Upload permissions). This occurs because a shell is used to execute df (i.e., with execSync instead of spawnSync in child_process in Node.js).

Recommendation

Update the hfs package to the latest compatible version. Followings are version details:

• Affected version(s): < 0.52.10
• Patched version(s): 0.52.10
