Microsoft Leaves On-Prem SharePoint Exposed to Zero-Day Attacks After Patch Failure
3 articles · Updated · The Register · Aug 18
Summary
On-prem SharePoint is under active zero-day attack after Microsoft’s patches failed to fully fix the underlying vulnerabilities.
Microsoft’s latest updates left exposed systems still vulnerable, turning what should have been a remediation into an ongoing security gap for self-hosted deployments.
The issue affects on-premises SharePoint rather than Microsoft’s cloud services, focusing risk on organizations that run the collaboration platform in their own environments.
The failed fix adds to a broader run of enterprise security concerns around Microsoft products, with defenders now facing exploitation before a complete patch is available.
