The camera should never face the public internet. Put it behind a VPN or a Zero-Trust tunnel. If you must allow remote viewing, use Axis’s AVHS (Axis Video Hosting System) service, which brokers the connection without opening ports on your firewall.

One particular dork has circulated in niche security forums and red-team playbooks for years:

Standard Axis cameras run on port 80 or 443. But many video servers run on non-standard ports. By adding "exclusive," researchers discovered that Axis servers using ActiveX controls or older Java applets for video viewing generate unique URL structures when a user has "exclusive viewing rights."

An attacker using this string is hoping to find device firmware version 4.x or 5.x. In these versions, the indexframe.shtml file calls a secondary file called exclusive_mode.shtml . If that file is accessible without authentication (due to a misconfigured access control list), the attacker triggers a session where the camera stops streaming to other users and begins streaming exclusively to the attacker.

This is not a traditional buffer overflow; it is a rooted in the device's design assumption that "whoever finds this page is the administrator." Part 5: The Offensive vs. Defensive Divide As an ethical researcher, you might find 50 cameras using this dork. Here is how to categorize your findings:
