Beginning
Is your company using Microsoft SharePoint? If so, you can’t ignore 2025. As hackers get more advanced, the focus is back on the growing number of SharePoint vulnerabilities that have put important company data at risk in several fields. It’s important to keep up with the latest security holes, whether you’re in charge of an on-premise server or using SharePoint Online. This tutorial tells you all you need to know, from CVE warnings to patching suggestions and how to avoid risks. You need to know how to keep your systems safe from these changing dangers if you operate a business, work in IT, or are a developer. Let’s look at the risks that SharePoint will face in 2025.
What is Microsoft SharePoint and why do so many people use it?
Businesses, governments, and institutions all use Microsoft SharePoint, a powerful web-based collaboration tool. It lets teams build websites, handle documents, automate tasks, and keep data safe. It works well with Microsoft 365, whether it’s on-premises or in the cloud, making it one of the best options for managing enterprise content.
But hackers pay attention to things that are used a lot. As more businesses rely on SharePoint, it becomes a more appealing target for attackers.
What are the weaknesses in SharePoint? A Simple Explanation
A SharePoint vulnerability is a hole or weakness in the platform that hackers can use to get in without permission, run harmful code, or steal data. These can come from:
- Old patches
- Permissions that are set up wrong
- Integrations with third parties that aren’t safe
- Bad firewall protection
Vulnerabilities don’t just show up out of nowhere; they often grow over time because of bad maintenance or the discovery of new CVEs.
Big SharePoint Security Flaws Found in 2025 (With CVEs)
There have already been a number of high-risk CVEs this year that have to do with Microsoft SharePoint:
- CVE-2025-1068 is a Remote Code Execution (RCE) vulnerability that lets attackers get into the system.
- CVE-2025-1123: SharePoint Server 2019 lets users get more privileges.
- CVE-2025-1250: A bug in SharePoint Online that lets information leak out.
These flaws affect both SharePoint Online and on-premises installations, thus repairs need to be made right away.
How do hackers take use of SharePoint’s flaws?
Hackers utilize a number of methods to take advantage of SharePoint bugs:
- Remote Code Execution (RCE): Uploading harmful files to run commands on the system level.
- SQL Injection: Getting to data using input fields that aren’t really secure.
- Phishing links on SharePoint: Links that look like they come from safe sites but are actually housed on hacked ones.
- Privilege Escalation: Getting admin rights from a regular user account.
These approaches make it easy to get into critical business data, implant malware, or even take full control of SharePoint servers.
SharePoint Breaches in the Real World (Case Studies)
In early 2025, a U.S. healthcare provider had a data leak since they hadn’t fixed a problem with its SharePoint instance. More than 200,000 records were made public.
A European financial company was hit by ransomware after hackers took advantage of an RCE hole in their SharePoint server.
Both of these incidents show how bad it is to not install security updates.
Is there a chance that your SharePoint installation could be in danger? Important Warning Signs to Look For
Look out for these signs:
- Your SharePoint Server is 2016 or older.
- There have been no updates in the previous 60 days.
- There is no MFA (Multi-Factor Authentication) set up.
- There are logins that look suspicious in audit trails.
- Strange file uploads or traffic spikes.
If any of these sound familiar, your SharePoint system might be in a lot of danger.
How to safely patch the newest SharePoint security holes
To keep your system safe, do this:
- Go to Microsoft’s official Security Update Guide.
- Search for CVE IDs like CVE-2025-1068.
- Install the patches that are suggested.
- Restart the servers and check the services.
Before putting fixes into production, always test them in a staging environment.
The Best Tools for Scanning and Watching SharePoint for Exploits
Use these highly rated tools:
- Microsoft Defender for Endpoints
- Acunetix Vulnerability Scanner
- Qualys Web Application Scanning
- Burp Suite for penetration tests that you make yourself
These enable you look for both known and unknown SharePoint risks in real time.
Ways to keep your SharePoint server safe in 2025
Do the following:
- Turn on Multi-Factor Authentication (MFA)
- Limit access by giving people different roles.
- Check logs and admin activity on a regular basis
- Encrypt all communications that take place inside SharePoint
- Set up rules for firewalls and intrusion detection
Good security isn’t just one thing; it’s an ongoing effort.
How often does Microsoft send out security updates for SharePoint?
On the second Tuesday of every month, Microsoft releases Patch Tuesday updates. Out-of-band patches might also include urgent fixes.
To stay up to speed on changes, keep your subscription to Microsoft Security Notification Services.
What Businesses Should Do After a SharePoint Security Breach
Right away, you should isolate the server that is having problems.
Check logs for signs of unauthorized access.
Change the passwords for all admin users.
Tell the stakeholders and the legal teams.
Make the changes and write down the breach.
Long-term: do complete evaluations of what happened and improve cybersecurity rules.
Which is safer in 2025: SharePoint On-Prem or Online?
| Function | SharePoint on the web | SharePoint On-Prem |
| Updates | Updates for SharePoint On-Prem are done automatically by Microsoft, but patches must be done by hand. | |
| Control of Access | MFA, Azure AD, and Conditional Access | Custom setup, monitoring, and integration with Microsoft Defender are all possible, but you will need third-party solutions. |
Overall, SharePoint Online is a safer choice for enterprises that want automatic protection.
Final Thoughts: Why It’s Dangerous to Ignore SharePoint Security Holes
A single hole in SharePoint that hasn’t been fixed might let gigabytes of critical data out, hurt your brand’s reputation, and even get you in trouble with the police. Cyberattacks are faster and smarter than ever in 2025.
What is your best defense? Keep up with the news, scan constantly, and don’t wait for an attack to happen. Taking action now will spare your business heartache later.
