CVE-2024-39943
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).
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 39.5%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
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).
