This detection rule is designed to identify systems that remain vulnerable to the Spectre and Meltdown vulnerabilities, specifically focusing on three CVEs: CVE-2017-5753, CVE-2017-5715, and CVE-2017-5754. By utilizing Splunk's data model for Vulnerabilities, the rule scans for entries relating to these specific CVEs, leveraging timestamps to identify when vulnerabilities were first and last noted. Once detected, the rule can help organizations prioritize patching and remediation efforts for systems that have not been updated against these recognized vulnerabilities. However, it is important to consider that some scanners might not accurately reflect whether the necessary patches have been applied, which can lead to false positives. This rule requires ingestion of vulnerability scanner data that reports applicable CVEs, indicating a proactive stance towards managing endpoint security risks. The rule has been marked deprecated, signaling that while the vulnerabilities remain relevant, alternative methods or tools may be recommended for ongoing detection and management.
