Regarding the #Cisco #IOS XE web UI RCE vuln, I wanted to test a few things in a lab environment to help with forensics, detection, etc. But the software is #proprietary and it seems Cisco tries quite hard to make it inaccessible to anyone not paying them. So it's a challenge for #defenders to get some basic answers from a device they control and know is not compromised.

Mass scanning a bit too hard for exposed #Cisco IOS XE got me a temporary block from #Hetzner.

Most devices in #Shodan seem implanted. Those not in Shodan not so much.

Go mitigate your #Cisco IOS XE routers right how. There's a #0day being exploited since September. You'll also need to assess if they are already compromised or not. What a mess.
