CVE-2024-7399 Samsung MagicINFO 9 Server: dangerous file upload

In plain words: The program accepts files it should refuse, such as programs disguised as ordinary uploads. The attacker can place and run their own tools on the server.

Confirmed exploited by CISA on · US federal patch deadline May 8, 2026

What to do

  1. Install Samsung's security update for MagicINFO 9 Server. If no update exists, follow the vendor's workaround or stop using the product until one ships.
  2. Install system updates the day they come out — most phone zero-days are fixed in a point release.
  3. Restart your phone every few days; some spyware does not survive a reboot.
  4. If you are a journalist, activist, lawyer, politician or executive, turn on Lockdown Mode (iPhone) or Advanced Protection (Android).
