CVE-2023-33963
📋 TL;DR
This CVE describes a deserialization vulnerability in DataEase, an open source data visualization tool, that allows remote attackers to execute arbitrary code on affected systems. All DataEase installations prior to version 1.18.7 are vulnerable. The vulnerability affects the datasource component and can be exploited without authentication.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with full remote code execution, allowing attackers to install malware, exfiltrate data, pivot to other systems, or establish persistent access.
Likely Case
Remote code execution leading to data theft, system takeover, or deployment of ransomware/cryptominers on vulnerable DataEase instances.
If Mitigated
Limited impact if proper network segmentation, least privilege, and monitoring are in place, though code execution would still be possible.
🎯 Exploit Status
Deserialization vulnerabilities typically have low exploitation complexity once details are known. No public exploit code has been identified at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.18.7
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-m26j-gh4m-xh9f
Restart Required: Yes
Instructions:
1. Backup your DataEase configuration and data
2. Stop the DataEase service
3. Upgrade to version 1.18.7 or later using the official release
4. Restart the DataEase service
5. Verify the upgrade was successful
🧯 If You Can't Patch
- Implement strict network access controls to limit DataEase exposure to only trusted networks
- Deploy web application firewall (WAF) rules to detect and block deserialization attack patterns
🔍 How to Verify
Check if Vulnerable:
Check the DataEase version in the web interface or configuration files. If version is below 1.18.7, the system is vulnerable.Check Version:
Check the DataEase web interface admin panel or examine the application version in the deployment configuration.Verify Fix Applied:
After upgrading, verify the version shows 1.18.7 or higher in the web interface or via the version check command.📡 Detection & Monitoring
Log Indicators:
- Unusual deserialization errors in application logs
