Microsoft SharePoint Faces Zero-Day Attacks After Patch Fails to Fix On-Prem Flaws
3 articles · Updated · The Register · Aug 14
Summary
On-premises SharePoint servers are under active zero-day attack after Microsoft's latest patches failed to fully fix the vulnerabilities.
Microsoft acknowledged the patch failure, leaving organizations that run SharePoint on their own infrastructure exposed despite applying the update.
The issue is limited to on-prem SharePoint rather than Microsoft's cloud-hosted services, sharpening the risk for enterprises managing their own servers.
The failed fix turns a routine patch cycle into an active security incident, likely forcing defenders to seek mitigations or wait for a corrected update.
