⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, privilege escalation, and potential remote code execution through database functions.
Likely Case
Data exfiltration from the database, unauthorized data modification, and potential authentication bypass.
If Mitigated
Limited impact with proper input validation and parameterized queries in place, though some risk remains if other vulnerabilities exist.
🎯 Exploit Status
SQL injection typically has low exploitation complexity. The vulnerability is in a publicly accessible endpoint with user-supplied input.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check latest Emoncms release or commit fixing issue #1916
Vendor Advisory: https://github.com/emoncms/emoncms/issues/1916
Restart Required: No
Instructions:
1. Update Emoncms to the latest version. 2. Apply the fix from the GitHub issue #1916 if updating isn't possible. 3. Verify the fix by testing the vulnerable endpoint.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and sanitization for the data query parameter in the /feed/insert.json endpoint.
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection rules to block malicious requests to the vulnerable endpoint.
🧯 If You Can't Patch
- Restrict access to the /feed/insert.json endpoint using network ACLs or authentication.
- Monitor logs for unusual SQL queries or access patterns to the vulnerable endpoint.
🔍 How to Verify
Check if Vulnerable:
Test the /feed/insert.json endpoint with SQL injection payloads in the data parameter. If the application returns database errors or unexpected behavior, it may be vulnerable.Check Version:
Check the Emoncms version in the application's admin panel or configuration files.Verify Fix Applied:
After patching, retest with SQL injection payloads. The application should reject or sanitize the input without executing SQL commands.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Errors related to SQL syntax from the /feed/insert.json endpoint
