Re: [c-nsp] TIL: Maintenance Operations Protocol (MOP)

AAA was unconfigured as I was testing on a lab router. Whether or not it provides unauthorized access depends on whether you expect anyone that has something connected to that router to have access to the console or not. At the very least it provides an opportunity and a vector. It doesn't

Hello, Sorry for the noise if you are all aware of what MOP is but if you aren't aware of what it is and use Cisco products (especially in a multi-tenant environment) it may be a good idea to read about it and evaluate any impact it may or may not have on your environment. Have a nice day =)
