CVE-2024-39943: Rejetto HTTP File Server

High severity, CVSS 8.8. EPSS: 39.5% chance of exploitation in the next 30 days.

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).

Affected products

  • Rejetto HTTP File Server: before 0.52.10 (fixed in 0.52.10)
