Main Idea

Microsoft has released emergency patches for vulnerabilities in its on-premises SharePoint software, while the cloud-based version remains unaffected.

Key Points

1. The vulnerabilities affect on-premises installations of SharePoint, not the cloud-based SharePoint 365.

2. The vulnerabilities, labeled CVE-2025-53770 and CVE-2025-53771, were exposed by Netherlands-based Eye Security.

3. The flaws could allow attackers to execute code over the network.

4. Over 200,000 organizations and 190 million people use SharePoint for content management.

5. Microsoft faced scrutiny from the U.S. Congress in 2024 for a series of cybersecurity issues.

Description

SharePoint’s cloud-based platform remains unaffected, with the vulnerabilities limited to on-premises installations, Microsoft said.
