Vulnerability Scans for Older Cisco IOS Vulnerability / Opt-Out Headers, (Thu, Nov 5th)
MentionsCisco
This morning, I was browsing our honeypot data for any new and existing PHP exploit attempts. Instead, I first ran into some GeoServer exploits, but found them to be too boring to write up. This Cisco IOS exploit attempt was a bit more interesting. Still nothing new. I suspect this is for CVE-2023-20198.
