Actively exploited Windows Update system downgrade vulnerability fixed.
Nearly 80 security vulnerabilities have been addressed by Microsoft as part of this month's Patch Tuesday, four of which were actively exploited zero-days, reports SC US.
Immediate remediation has been urged for the zero-days; the most severe of which was a Windows Update system downgrade vulnerability, tracked as CVE-2024-43491, which was noted by the Trend Micro Zero Day Initiative to be actively exploited despite Microsoft's denial.
"It's also interesting to note that while this particular bug isn't being exploited in the wild, it allowed some of those Optional Components to be exploited. The only good news here is that only a portion of Windows 10 systems are affected," said ZDI's Dustin Childs.
