CVE-2023-4229Network attack vector

Unintended web actions via missing frame restrictions

Published Aug 24, 2023 · Updated Oct 1, 2024

Clickjacking in Moxa ioLogik 4000 Series firmware 1.6 and earlier allows remote attackers to induce unintended web actions. The web service omits session headers that restrict cross-origin framing, allowing a malicious page to overlay or embed the device interface. Exploitation requires a user with an active device session to interact with attacker-controlled content; the published assessment limits direct impact to unintended integrity changes.
