CVE-2025-49001
📋 TL;DR
CVE-2025-49001 is a critical authentication bypass vulnerability in DataEase where JWT token secret verification fails, allowing attackers to forge valid authentication tokens using any secret. This affects all DataEase deployments prior to version 2.10.10. Attackers can gain unauthorized access to business intelligence data and system functionality.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to access all data, modify dashboards, execute arbitrary code, and pivot to other systems in the network.
Likely Case
Unauthorized access to sensitive business intelligence data, data exfiltration, and manipulation of reports and visualizations.
If Mitigated
Limited impact if strong network segmentation, monitoring, and additional authentication layers are in place.
🎯 Exploit Status
Exploitation requires understanding JWT token structure but tools exist to automate token forgery.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.10.10
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-xx2m-gmwg-mf3r
Restart Required: Yes
Instructions:
1. Backup your DataEase instance and data. 2. Download version 2.10.10 from official repository. 3. Stop DataEase service. 4. Replace with patched version. 5. Restart DataEase service. 6. Verify JWT tokens now require proper secret verification.
🧯 If You Can't Patch
- Implement network-level access controls to restrict DataEase access to authorized users only.
- Deploy a web application firewall (WAF) with JWT validation rules to block forged tokens.
🔍 How to Verify
Check if Vulnerable:
Check DataEase version via web interface or configuration files. If version is below 2.10.10, the system is vulnerable.Check Version:
Check DataEase web interface admin panel or examine application configuration files for version information.Verify Fix Applied:
Attempt to forge a JWT token with an incorrect secret and verify authentication fails. Valid tokens with correct secret should still work.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts with malformed JWT tokens
- Successful logins from unusual IP addresses or user agents
- Multiple authentication attempts with different tokens
Network Indicators:
- Unusual API calls to DataEase endpoints
- Traffic patterns indicating data exfiltration
- Authentication requests with manipulated JWT headers
