Technical Analysis

There is an exploit for this. I was able to extract the firmware and statically confirm the vulnerability. I haven’t tried to kick it off in QEMU yet.

Fun bug chain. The vendor hasn’t patched this. If you’re using this in your environment, you may want to disable the web interface as per the exploit’s README.md.

Note that this HiveOS is not to be confused with the mining platform HiveOS. This is Wi-Fi stuff.
