Microsoft Patches Fail to Stop SharePoint Zero-Day Attacks on On-Prem Servers
3 articles · Updated · The Register · Jul 6
Summary
On-prem SharePoint servers are now under zero-day attack after Microsoft-issued patches failed to close the underlying vulnerabilities.
Microsoft’s fix breakdown leaves self-hosted SharePoint deployments exposed, making organizations that run the software in their own environments the immediate target.
The report centers on patch failure rather than cloud services, underscoring that the risk is concentrated in on-prem installations.
The episode adds to pressure on Microsoft’s security response as enterprises weigh whether emergency mitigations or broader changes to on-prem software use are needed.
