Even if the owner changes the password, some main.cgi implementations have undocumented backdoor accounts or command injection flaws (e.g., CVE-2018-10660, CVE-2021-33014). The very presence of the script implies a certain age and vulnerability.
The intitle:"network camera" inurl:"main.cgi" dork was far more potent 5–10 years ago. Today, Google has rate-limited and restricted some advanced operators (especially link: and allinurl:). Additionally, most modern cameras use:
However, legacy systems persist. Factories, prisons, hospitals, and small businesses often run outdated hardware for a decade or more. As long as there is a main.cgi on the public web, this dork remains a valuable tool for security auditors and a persistent risk for the unprepared. intitle network camera inurl maincgi link
Many devices indexed do not require any login. The camera video stream can be accessed directly via:

Many results lead to a login page. Using default credential lists (e.g., admin:admin, admin:1234, root:root) often grants access. The famous main.cgi page on some Trendnet cameras had a hardcoded backdoor user (supervisor). However, legacy systems persist
Accessing a camera discovered via this search query without explicit permission violates:
Security researchers should use such dorks only for:
Universal Plug and Play often auto-forwards ports without your knowledge. Disable UPnP on both the camera and your router.
Unsecured network cameras are prime targets for botnets like Mirai. Attackers scan for devices with default credentials, infect them, and use them to launch massive DDoS attacks. Your camera becomes a weapon.
