CRITICAL · CVSS 3.1 · EPSS 39.5% (pctl 99)
Patch early
EPSS 39.5% — above the 10% action threshold.
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).
