For the past 3 days, I was looking for a way to make changes to the classic’s theme CSS. As an amateur, I thought that if I make the changes I want to the files that are located on the _dev directory inside my theme, changes will be converted to CSS……. WRONG !!!
So I started looking harder. There are many solutions on the internet. Some almost worked, some not, some were to complicated to understand. After spending hours and hours o this, I final made it. So here it goes.
Cisco announced a remote code execution vulnerability that affects telnet on catalyst series devices. Once again this has to do with the documents leaked by Wikileaks, known as Vault 7.
Cisco recommends to enable only SSH access on the devices affected, if possible. For devices that do not support SSH, VTY access lists may be applied to reduce the risk.
More information about the vulnerability and the devices affected, can be found here.
