cgi-bin/luci

Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.

You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.

What is this endpoint?

cgi-bin/luci

OpenWrt LuCI web-interface CGI endpoint

What an attacker could do

Identifies an OpenWrt router running the LuCI interface; unauthenticated or CVE-vulnerable LuCI versions can allow command injection or auth bypass, giving full control of the router and its traffic.

How to defend it

Restrict LuCI to the LAN/management interface only, keep OpenWrt firmware patched, and require strong admin credentials so the CGI endpoint is never reachable from the WAN.
