CVE-2024-46985
📋 TL;DR
DataEase versions before 2.10.1 contain an XML external entity injection (XXE) vulnerability in the static resource upload interface. This allows attackers to read arbitrary files from the server and potentially perform network reconnaissance of internal systems. All DataEase deployments using vulnerable versions are affected.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise through file system access, credential theft from configuration files, and lateral movement within the internal network.
Likely Case
Unauthorized reading of sensitive files (configuration, credentials, source code) and internal network scanning.
If Mitigated
Limited impact if proper network segmentation and file permissions are configured, though file reading may still be possible.
🎯 Exploit Status
XXE vulnerabilities are well-understood with standard payloads available. The advisory confirms exploitation vectors for file reading and intranet detection.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.10.1
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-4m9p-7xg6-f4mm
Restart Required: Yes
Instructions:
1. Backup your DataEase configuration and data. 2. Download DataEase v2.10.1 from the official repository. 3. Stop the DataEase service. 4. Replace the installation with v2.10.1. 5. Restart the DataEase service. 6. Verify the version is now 2.10.1.
🔧 Temporary Workarounds
Disable XXE Processing
allConfigure XML parsers to disable external entity processing
Modify DataEase XML parser configuration to set: FEATURE_SECURE_PROCESSING = true, DISALLOW_DOCTYPE_DECL = true
Restrict Upload Interface Access
linuxBlock external access to the static resource upload endpoint using network controls
Add firewall rule: iptables -A INPUT -p tcp --dport [DataEase-port] -m string --string "static/upload" --algo bm -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate DataEase from sensitive internal systems
- Deploy a web application firewall (WAF) with XXE protection rules enabled
🔍 How to Verify
Check if Vulnerable:
Check if DataEase version is below 2.10.1 via the web interface or configuration files
Check Version:
Check the DataEase web interface admin panel or examine the application version in configuration files
Verify Fix Applied:
Confirm version is 2.10.1 or higher and test the upload interface with XXE payloads (in a controlled environment)
📡 Detection & Monitoring
Log Indicators:
- XML parsing errors with external entity references
- Unusual file access patterns from upload endpoints
- Large XML payloads in upload requests
Network Indicators:
- HTTP POST requests to static upload endpoints containing XML entities
- Outbound connections from DataEase to internal systems following upload requests
