CVE-2023-31936
📋 TL;DR
This SQL injection vulnerability in Rail Pass Management System v1.0 allows remote attackers to execute arbitrary SQL commands via the viewid parameter. Attackers can potentially read, modify, or delete database contents, and in some cases execute arbitrary code on the server. Organizations using this specific version of the rail pass management software are affected.
💻 Affected Systems
- Rail Pass Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the database server leading to data theft, data destruction, and potential remote code execution on the underlying server.
Likely Case
Unauthorized access to sensitive passenger data, modification of rail pass records, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing without modification.
🎯 Exploit Status
Simple parameter manipulation in HTTP requests, no authentication required
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
No official patch available. Implement parameterized queries and input validation in view-pass-detail.php
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns in viewid parameter
Input Validation Filter
allAdd server-side validation to only accept numeric values for viewid parameter
Add PHP validation: if(!is_numeric($_GET['viewid'])) { die('Invalid input'); }
🧯 If You Can't Patch
- Isolate the Rail Pass Management System behind a reverse proxy with strict input validation
- Implement network segmentation to limit database server access only to the application server
🔍 How to Verify
Check if Vulnerable:
Test view-pass-detail.php with malicious viewid parameter like: viewid=1' OR '1'='1Check Version:
Check application version in admin panel or readme filesVerify Fix Applied:
Test with same SQL injection payloads and verify they are rejected or sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed parameter validation attempts
Network Indicators:
- HTTP requests to view-pass-detail.php with SQL keywords in parameters
SIEM Query:
source="web_logs" AND uri="*view-pass-detail.php*" AND (param="*viewid=*'*" OR param="*viewid=*%27*")
