CVE-2024-56511
📋 TL;DR
This vulnerability allows attackers to bypass authentication in DataEase by exploiting a path traversal flaw in the whitelist validation logic. When the application is deployed with a custom context path, attackers can access protected interfaces without authentication. All DataEase deployments prior to version 2.10.4 are affected.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing unauthorized access to all data visualization dashboards, sensitive data exposure, and potential data manipulation or deletion.
Likely Case
Unauthorized access to protected dashboards and data sources, leading to data exfiltration and privacy violations.
If Mitigated
Limited impact with proper network segmentation and access controls, but still potential for unauthorized data viewing.
🎯 Exploit Status
Exploitation requires knowledge of the custom context path, but the bypass technique is straightforward once known
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.10.4
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-9f69-p73j-m73x
Restart Required: Yes
Instructions:
1. Backup your DataEase instance and data. 2. Download version 2.10.4 or later from the official repository. 3. Replace the existing installation with the patched version. 4. Restart the DataEase service.
🔧 Temporary Workarounds
Remove custom context path
allDeploy DataEase without setting 'server.servlet.context-path' configuration parameter
Remove or comment out 'server.servlet.context-path' from application configuration files
Network access restriction
linuxRestrict access to DataEase web interface using firewall rules
iptables -A INPUT -p tcp --dport 8080 -s trusted_network -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation and only allow trusted IP addresses to access the DataEase interface
- Deploy a web application firewall (WAF) with path traversal protection rules
🔍 How to Verify
Check if Vulnerable:
Check if running DataEase version < 2.10.4 AND has custom context path configured in application properties
Check Version:
Check DataEase web interface footer or application logs for version information
Verify Fix Applied:
Verify version is 2.10.4 or later and test authentication bypass attempts with /geo/../context-path/ patterns
📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing '/geo/../' patterns
- Authentication failures followed by successful access to protected resources
- Requests with unusual path traversal sequences
Network Indicators:
- HTTP requests with path traversal sequences targeting DataEase endpoints
- Unauthenticated access to normally protected API endpoints
