Honeypot captures suspected Cisco IOS exploit attempt from RootEvidence scanner

Honeypot telemetry recorded a POST to /%77ebuiwsmahttps on port 8000 carrying a WSMA execCLI SOAP payload that runs 'uname -a' using the admin account, with a placeholder password. The researcher suspects CVE-2023-20198 but the article does not confirm it. The User-Agent was RootEvidence/1.0, which sent Opt-Out-Email and Opt-Out-Url headers and URL-encoded the 'w' in the path. Defenders should check whether their Cisco IOS management interfaces are exposed and review logs for requests to this path.
