I asked Kimi to enable ipv6 in the background as I was doing something else.
Turns out it was not enabled on my router so, not having the admin password, it naturally then found the firmware online, decrypted it, extracted the lua bytecode, found out the opcodes were shuffled, updated the decompiler to work with it and found a stack-overflow in a binary it launched to get access.
Still didn't succeed though, since it figured attempting to trigger it would be ""crashing = disruption"" 😭

As part of a routine product assessment, we discovered and disclosed four disruptive vulnerabilities affecting 22 different Ubiquiti products.
The worst part? No firewall rule could prevent it.

A great example of hidden attack surfaces - two packets through the dataplane and your network is dead... 🪦
Are you too a firewall ignition expert?
