CVE-2024-1491Public exploitNetwork attack vector

Unauthenticated code execution via MPFS image upload

Published Apr 18, 2024 · Updated Aug 1, 2024

Missing authentication in Electrolink transmitter web interfaces allows remote attackers to execute code through an MPFS image upload. The unauthenticated /upload endpoint accepts an MPFS binary and writes it into flash that backs the HTTP2 web server. Network access to the web interface is sufficient; exploitation changes stored web content and permits attacker-supplied code execution.
