This disclosure comes amidst Microsoft's ongoing efforts to address two other zero-day flaws (CVE-2024-38202 and CVE-2024-21302) that could potentially bypass Windows security updates and reintroduce old vulnerabilities. Moreover, Elastic Security Labs recently unveiled various methods that attackers can exploit to run malicious apps without triggering Windows Smart App Control and SmartScreen warnings.
Although Microsoft has assessed the exploitation of this vulnerability as "Less Likely," users are strongly encouraged to update their systems with the final patch when it becomes available for optimal protection. Staying vigilant and adopting proactive security measures is crucial in the face of evolving cyber threats.
