Microsoft Urgently Addresses Critical SharePoint 2016 Vulnerabilities Following Active Exploitation
Redmond, WA – July 22, 2025 – Microsoft has issued an urgent out-of-band patch for its SharePoint Server 2016 product, addressing critical security vulnerabilities that have reportedly been actively exploited by malicious actors. The advisory, published today, highlights the severity of these flaws and emphasizes the immediate need for administrators to apply the provided updates.
The vulnerabilities, which were detailed in The Register’s reporting earlier today, are described as zero-day exploits, meaning they were unknown to Microsoft and unpatched at the time of their discovery and exploitation. This makes them particularly dangerous as they leave systems exposed and vulnerable to attack without readily available defenses.
While specific technical details regarding the nature of the exploits are typically withheld by Microsoft to prevent further malicious activity, the company’s prompt action indicates that the potential impact could be significant. Such vulnerabilities can often be leveraged for a range of nefarious purposes, including unauthorized access to sensitive data, disruption of services, or the execution of arbitrary code on affected servers.
SharePoint Server is a widely used platform for collaboration, document management, and internal business processes within many organizations. The active exploitation of these vulnerabilities means that any organization running SharePoint Server 2016 that has not yet applied the update is at risk.
Microsoft strongly advises all users and administrators of SharePoint Server 2016 to prioritize the deployment of this critical patch. The company’s security bulletins typically provide detailed instructions on how to identify affected systems and apply the necessary updates. It is also a good practice for organizations to maintain a robust patch management strategy to ensure their systems are consistently protected against emerging threats.
This incident serves as a stark reminder of the ongoing cybersecurity landscape and the importance of staying vigilant. Promptly addressing security advisories from vendors like Microsoft is crucial in safeguarding organizational data and maintaining the integrity of IT infrastructure. Organizations are encouraged to consult Microsoft’s official security advisories for the most up-to-date information and guidance on applying this critical patch.
