CVE-2023-37258
📋 TL;DR
DataEase versions before 1.18.9 contain a SQL injection vulnerability that bypasses blacklist protections, allowing attackers to execute arbitrary SQL commands. This affects all deployments using vulnerable versions of the DataEase data visualization tool. The vulnerability could lead to data theft, manipulation, or complete system compromise.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, data destruction, privilege escalation, and potential remote code execution on the underlying server.
Likely Case
Unauthorized data access and extraction from connected databases, potentially exposing sensitive business information or personal data.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permission restrictions in place.
🎯 Exploit Status
SQL injection vulnerabilities are well-understood attack vectors. While no public PoC exists, the vulnerability type suggests straightforward exploitation for attackers with SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.18.9
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-r39x-fcc6-47g4
Restart Required: Yes
Instructions:
1. Backup your DataEase instance and databases. 2. Download version 1.18.9 or later from the official repository. 3. Stop the DataEase service. 4. Replace the existing installation with the patched version. 5. Restart the DataEase service. 6. Verify the version is now 1.18.9 or higher.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate DataEase instances from sensitive databases and other critical systems.
- Deploy a web application firewall (WAF) with SQL injection protection rules and enable strict input validation.
🔍 How to Verify
Check if Vulnerable:
Check the DataEase version in the web interface or configuration files. If version is below 1.18.9, the system is vulnerable.Check Version:
Check the DataEase web interface admin panel or examine the application configuration files for version information.Verify Fix Applied:
After patching, verify the version shows 1.18.9 or higher in the web interface or configuration.📡 Detection & Monitoring
