CVE-2024-49039 - vulnerability in Windows Task Scheduler that can lead to elevation of privilege
Why You Should Care?
Zero-day vulnerabilities are vulnerabilities where a flaw has been identified but there was no fix for the flaw, which means attackers will try to exploit as many targets as possible before users fix the vulnerability. This makes it extra dangerous, and needs to be addressed as soon as possible.
In this case, 2 of the zero-days are already being exploited, which means it is only a matter of time before the attackers compromise your business. Now that patches are available, it is critical to apply the patches as soon as possible to avoid getting compromised.
What Should You Do?
Test the patches ASAP at your organization, and make sure it does not break any business applications
Prioritize patching against the 2 actively exploited zero-days
Next priority are the other zero-days
Roll out the rest of the Patch Tuesday updates
