CVE-2025-53639
📋 TL;DR
This SQL injection vulnerability in MeterSphere allows attackers to execute arbitrary SQL commands through the sortField parameter in API endpoints. This could lead to data theft, modification, or deletion, potentially compromising the entire database. All MeterSphere instances running versions before 3.6.5-lts are affected.
💻 Affected Systems
- MeterSphere
📦 What is this software?
Metersphere by Metersphere
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data exfiltration, modification, deletion, or potential remote code execution via database functions.
Likely Case
Data extraction, modification of test results or configurations, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database user privilege restrictions.
🎯 Exploit Status
SQL injection via sort parameters is a well-known attack vector with many existing tools and techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.6.5-lts
Vendor Advisory: https://github.com/metersphere/metersphere/security/advisories/GHSA-vcm3-5w3f-9f45
Restart Required: Yes
Instructions:
1. Backup your MeterSphere instance and database. 2. Update to version 3.6.5-lts using your deployment method (Docker, Kubernetes, or manual). 3. Restart the MeterSphere service. 4. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation Web Application Firewall (WAF) Rule
allBlock requests containing SQL injection patterns in sortField parameter
WAF-specific configuration required
Database User Privilege Reduction
linuxLimit database user permissions to read-only for application queries
ALTER USER 'metersphere'@'%' WITH GRANT OPTION;
REVOKE ALL PRIVILEGES ON metersphere.* FROM 'metersphere'@'%';
GRANT SELECT ON metersphere.* TO 'metersphere'@'%';
🧯 If You Can't Patch
- Implement strict input validation for sortField parameter in application code
- Deploy a WAF with SQL injection detection rules
🔍 How to Verify
Check if Vulnerable:
Check if version is below 3.6.5-lts and test sortField parameter with SQL injection payloadsCheck Version:
docker exec metersphere cat /opt/metersphere/version.txt || check web interface About pageVerify Fix Applied:
Confirm version is 3.6.5-lts or higher and test that SQL injection attempts are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests with sortField containing SQL keywords
- Database query errors from unexpected sources
Network Indicators:
- HTTP requests with sortField parameter containing UNION, SELECT, INSERT, DELETE, or other SQL keywords
- Abnormal database connection patterns
SIEM Query:
source="metersphere.logs" AND ("sortField" AND ("UNION" OR "SELECT" OR "INSERT" OR "DELETE" OR "DROP" OR "--" OR "'"))
