Microsoft SharePoint Faces Zero-Day Attacks After 2 Patch Failures
3 articles · Updated · The Register · Jun 18
Summary
On-premises Microsoft SharePoint is under active zero-day attack after earlier security patches failed to close existing vulnerabilities.
Microsoft’s fixes left exposed systems still vulnerable, turning what should have been remediation into an opening for live exploitation.
The threat is limited to on-premises SharePoint rather than Microsoft’s cloud services, focusing risk on organizations running the software in their own environments.
The episode adds to pressure on Microsoft’s enterprise security response, showing how incomplete patching can quickly escalate into active attacks.
