CVE-2025-48998
📋 TL;DR
This vulnerability allows authenticated users in DataEase to bypass a previous patch and read/deserialize arbitrary files through the background JDBC connection. It affects DataEase installations prior to version 2.10.6. Organizations using vulnerable versions of this business intelligence tool are at risk.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Authenticated attackers could read sensitive files (configuration files, credentials, system files) leading to complete system compromise, data exfiltration, or lateral movement.
Likely Case
Authenticated users with malicious intent could access sensitive business data, configuration files, or other restricted information stored on the server.
If Mitigated
With proper authentication controls and network segmentation, impact is limited to authorized users who would need to exploit the vulnerability intentionally.
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of the JDBC connection mechanism. The advisory suggests this is a bypass of a previous patch.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.10.10
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-2wfc-qwx7-w692
Restart Required: Yes
Instructions:
1. Backup your DataEase configuration and data. 2. Download version 2.10.10 or later from the official repository. 3. Stop the DataEase service. 4. Replace the installation with the new version. 5. Restart the DataEase service. 6. Verify functionality.
🧯 If You Can't Patch
- Restrict access to DataEase to only trusted, authenticated users with minimal necessary privileges.
- Implement network segmentation to isolate DataEase servers from sensitive systems and data.
🔍 How to Verify
Check if Vulnerable:
Check the DataEase version in the web interface admin panel or configuration files. If version is below 2.10.6, the system is vulnerable.Check Version:
Check the web interface admin panel or examine the application configuration files for version information.Verify Fix Applied:
After upgrading, verify the version shows 2.10.10 or higher in the admin panel and test that JDBC connections function properly without allowing arbitrary file access.📡 Detection & Monitoring
Log Indicators:
- Unusual JDBC connection attempts
- Multiple file read operations through JDBC
- Access to files outside expected data directories
Network Indicators:
- Unusual database connection patterns from DataEase servers
- Traffic to unexpected file paths via JDBC protocols
SIEM Query:
source="dataease" AND (event="jdbc_connection" OR event="file_access") AND (path CONTAINS "/etc/" OR path CONTAINS "/root/" OR path CONTAINS "..")
