TPLink EX 220 (AX1800) #26

Open metrotyranno opened 2 years ago

metrotyranno commented 2 years ago

Hi,

This is unable to decrypt the config of the EX 220. Can someone help me get this config decrypted?

The script returns ERROR: Unrecognized file type!

I changed the script a bit so it returns the first 36 bytes:

b'\x83\xa1\x8d\x9ew\x84\xdb\x90M~\xc8\xecc\xa2\xa1\x16\xb9[\x9c\xd0o\x05\x90U@\xfc{\n\xa8)\x8f\xbf\x06\n\x17'

Can anyone help me get this decrypted?

Hi, that looks like a fairly recent TP-Link model. It's likely not using the same keys/methods of encryption/compression for its config files, so this project may not be appropriate. I quickly looked online and did not find a downloadable firmware for this product. TP-Link appears to also have "forgotten" to post the open source GPL licensed parts of their code for this router, you could make a request to them for it if you wish... I personally do not expect to attempt to "solve" this model. Good luck!

The device is basically an AX1800 with some ISP specific features. Would the GPL parts for the AX1800 offer any help?

Ah, :) I thought that was a Wi-Fi 6 chipset qualifier (802.11ax / AX, 1800 Mbps). I see now that TP-Link actually have an AX1800 model. Thanks. I could be wrong, but because it is fairly recent, I still suspect it might be using a different method for config files. Sorry, I can't see myself reverse engineering that firmware anytime soon.

I managed to get my hands on the firmware bin. Would this be helpful in solving the issue?

No, sorry, as I mentioned, I won't be personally reverse engineering those firmwares. This project targets a class of TP-Link routers using similarly encoded configuration files; it wouldn't be useful with config files using a completely different storage format. Cheers.
