Here we go again, this time with a new way to root the Cisco Meraki MR18. Note that this method will ONLY work on the MR18, and I am not responsible for any damaged devices if you want to try this on something else as it will not work!
If you haven’t noticed, in my spare time I really enjoy breaking into embedded devices for the fun of things. Over the past year, I have spent a ton of time rooting the Cisco Meraki MR18, and today I get the chance to publicly disclose my findings.
To start, let me note by saying I have properly disclosed this issue to Cisco Meraki months ago, but due to the fact they are no longer replying to my emails or honoring their own Bug Bounty, I have decided to publicly disclose this after waiting over 90 days since their last reply. Hopefully one of these days I will write up the process I used to find this “exploit”.
