What it detects
This rule detects running-configuration changes attributed to the SEP_webui_wsma_http user in Cisco IOS XE syslog. During exploitation of the Web UI vulnerability, configuration commits appeared as %SYS-5-CONFIG_P messages performed by SEP_webui_wsma_http, alongside %WEBUI-6-INSTALL_OPERATION_INFO ADD events. Configuration writes by this internal web-service account indicate abuse of the exposed management interface.
