CVE-2024-7399Samsung MagicINFO 9 Server — traversal to file write as system

Samsung MagicINFO 9 Server before 21.1050 lets a request escape its directory and write a file anywhere on the host with system authority — enough to plant an executable script and take over the signage server.

YOUR NEXT MOVE

Upgrade MagicINFO 9 Server to 21.1050 or later now; then sweep the web root for files you did not put there and rebuild the host if any turn up.
