Summary: New exploits in on-prem SharePoint highlight how patching leaves enterprises exposed to breaches and data loss. CAEVES provides a zero-trust alternative with immutable storage, automated versioning, and AI-driven security.
New Vulnerabilities Put Businesses at Risk
In July 2025, Microsoft confirmed active exploits targeting on-premises SharePoint Servers, exposing customers to serious security risks through four vulnerabilities:
- CVE-2025-49706 (Spoofing)
- CVE-2025-49704 (Remote Code Execution)
- CVE-2025-53770
- CVE-2025-53771
The alarm bells are loud, and they’re ringing for IT leaders, CISOs, and architects. If you’re still relying on legacy infrastructure for business-critical collaboration and file services, the message is clear: patching is no longer a sustainable security model for modern enterprises.
What Went Wrong and Why It Matters
These latest CVEs allow attackers to gain unauthorized access, impersonate users, and execute code remotely. Now the door is open to data exfiltration, ransomware payloads, or lateral movement inside your network. Worse still, businesses are being exploited by these vulnerabilities every second.
You can’t wait for Microsoft to patch the issue and solve the problem for you. Here are some key takeaways from the Microsoft Threat Intelligence blog:
- Attacks are targeting on-premises SharePoint environments, particularly those that are lagging on updates.
- Threat actors are chaining exploits with post-compromise techniques, meaning that even a brief exposure window can lead to long-term damage.
- Organizations that use outdated or unmonitored deployments are the most vulnerable.
And if you’re thinking, “We patched last quarter, we’re fine,” you’re missing the point.
Security teams are locked in a cycle of:
- Chase new vulnerabilities
- Deploy emergency patches
- Hope there were no breaches before the update
Meanwhile, modern attackers are utilizing automation, AI, and persistent infrastructure to scan, exploit, and evade at a larger scale.
Ask yourself:
- Can your team confidently say that your SharePoint deployment is always up to date?
- How quickly can you detect and recover from a breach?
- Are your SharePoint ASP.NET machine keys rotated regularly?
- Do you have auditable WORM compliance and immutable versioning for your critical data?
For many, the answer is no. You can’t wait for these issues to solve themselves; your data is too valuable to leave that risk unaddressed.
While SharePoint Online (in Microsoft 365) was not affected this time, on-prem deployments remain a liability. For businesses that require data sovereignty, deep archival, or hybrid cloud models, SharePoint’s architecture no longer delivers the control or confidence needed.
That’s where CAEVES comes in.
Meet CAEVES: Intelligent Deep Storage Without the Security Tradeoffs
CAEVES is for organizations that need:
✅ Immutable storage with built-in snapshotting
✅ Cloud-agnostic deployment: hybrid or public cloud
✅ Automated versioning & retention tiers for every file
✅ Real-time anomaly detection with native AI and threat analytics
✅ No ASP.NET keys to rotate, no IIS to harden, no outdated patching cycles
It’s not just a platform. It’s a new way to think about files as secure, searchable, AI-ready assets. And unlike SharePoint, CAEVES is designed for the zero-trust era, where control, visibility, and recovery are non-negotiable.
Next Steps: Get Ahead of the Next Breach
Security is no longer just about firewalls and antivirus; it’s about eliminating blind spots and hardening your core platforms.
Still running SharePoint Server on-prem? Don’t wait for the next security issue to spur you into action. Map out your exit strategy and explore new methods to secure your data. It’s time to embrace the future and utilize a storage platform that won’t expose your sensitive information to malicious actors.
