SharePoint Faces Zero-Day Attacks After Microsoft Patch Failures
3 articles · Updated · The Register · Jul 15
Summary
On-premises SharePoint is under active zero-day attack after Microsoft's earlier security patches failed to fully fix the underlying vulnerabilities.
Microsoft's failed remediation left self-hosted SharePoint deployments exposed, turning what should have been a patched flaw into an actively exploited security risk.
The issue affects on-prem SharePoint rather than Microsoft's cloud services, putting organizations that run the collaboration software in their own environments at immediate risk.
The episode adds to pressure on Microsoft to deliver a working fix quickly as enterprises reassess patch reliability for widely used on-prem infrastructure.
