Tools Introducing Mesquito (BETA) - The annoying WAF loader

Bluebotlabs · 07-16-2023, 02:48 PM

Hey, I'm Bluebotlabs, a while back I created KWebBrew, just a simple loader for offline WAF-like browser stuff.

Well, now I've created Mesquito (BETA), a REAL WAF Loader for non-jailbroken Kindles. That's right, it works on the latest firmware (5.16.2.1) and lets you run actual privilaged WAFs on the Kindle.

There are some limitations of course, these WAFs run within the context of the Kindle store, meaning that whilst you can use certain WAF APIs, you can only communicate with the following LIPC services:

com.lab126.pillow
com.lab126.chromebar
com.lab126.readnow

A private modification to Mesquito allows it to access all LIPC services (in theory) but it's experimental and not public at the moment.

As Mesquito is still BETA, it does not ship with any apps specifically for it, but it is backwards compatible with KWebBrew apps.

Documentation for Mesquito and other WAF-related info can be found here:
https://kindlemodding.github.io/docs/Mesquito/

Mesquito itself can be installed via the steps shown in the same link

I can't wait to see what the community creates with this!!!

Thank you for reading this rather long post,
Bluebotlabs

Hey Blue, Awesome work with Mesquito! Do you have any plans for a consolidated place to look through apps that other people have developed, such as a wiki page or a pinned thread?

Can we install Koreader or a similar reader like that?

At the moment Mesquito only allows you to run somewhat privellaged WAFs, we have a rudimentary privelage escallation trick in the works to gain more access to LIPC services, we can now query and write to all LIPC properties in a private beta

However, code execution remains out of bound for the time being so no full jailbreak at the moment, and therefore no koreader sadly

Stupid question: Do any of the WAF/LIPC services you have access to permit writing to the file system at an arbitrary location with root privilege? If so, you have the ability to JB right there.

Hah

If only it was that easy
also, you'd need code execution anyway since rootfs is mounted as readonly

Unfortunately I haven't found any LIPC service that offers FS writing or code execution (yet)
I'm going to work on decompiling and documenting the Kindle's Java Apps next
