Our analytic pinpoints exploitation by monitoring web requests to the "/cf_scripts/scripts/ajax/ckeditor/*" path. This focus helps differentiate malicious activity from standard ColdFusion traffic. For SOCs, detecting such attempts is vital given the vulnerability's CVSS score of 9.8, signaling its severity.
