📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including user credentials, payment information, and sensitive business data leading to data breach, financial loss, and regulatory penalties.
Likely Case
Attackers extract user credentials and sensitive data, potentially leading to account takeover and data exfiltration.
If Mitigated
With proper input validation and parameterized queries, the vulnerability is eliminated and no data exposure occurs.
🎯 Exploit Status
Public exploit script available on GitHub demonstrates SQL injection via HTTP requests to the vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes with parameterized queries.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting the view_plan endpoint.
WAF-specific configuration commands vary by vendor
Input Validation Filter
allAdd server-side validation to restrict id parameter to expected numeric values only.
Implementation depends on server technology (PHP, etc.)
🧯 If You Can't Patch
- Isolate the application behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from the application server
🔍 How to Verify
Check if Vulnerable:
Test the view_plan endpoint with SQL injection payloads (e.g., id=1' OR '1'='1) and observe database errors or unexpected responses.Check Version:
Check application version in source code or configuration files (typically in about.php or similar files).Verify Fix Applied:
After implementing fixes, retest with SQL injection payloads and confirm proper error handling or rejection of malicious input.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple requests to view_plan with suspicious id parameters
Network Indicators:
- HTTP requests to /view_plan containing SQL keywords (UNION, SELECT, etc.) in parameters
SIEM Query:
source="web_logs" AND uri="/view_plan" AND (param="*UNION*" OR param="*SELECT*" OR param="*OR*1*" OR param="*'*" OR param="*--*")
