Hot Take:

Schneider Electric’s ATV 630 device has a Cross-Site Scripting vulnerability, and it seems the “Life Is On” in more ways than they intended. Someone should tell them “Life is On” without a security patch is more like “Life is Off, and the hackers are in!”

Key Points:

  • A Cross-Site Scripting vulnerability has been identified in Schneider Electric’s ATV 630.
  • The vulnerability allows attackers to inject JavaScript via the ClientNonce parameter.
  • Exploitation can lead to session hijacking.
  • No fix is currently available, but a firmware update is on the horizon.
  • CyberDanube Security Research is recommending a full security review.
