CVE-2023-48685
📋 TL;DR
CVE-2023-48685 allows unauthenticated attackers to execute arbitrary SQL commands through the 'psd' parameter in Railway Reservation System v1.0's login.php. This can lead to data theft, authentication bypass, or complete system compromise. All deployments of Railway Reservation System v1.0 are affected.
💻 Affected Systems
- Railway Reservation System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, authentication bypass, privilege escalation, and potential remote code execution on the underlying server.
Likely Case
Unauthenticated attackers extracting sensitive user data (passwords, personal information), bypassing authentication to gain admin access, or manipulating reservation data.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation preventing database access from external sources.
🎯 Exploit Status
SQL injection via login.php 'psd' parameter requires no authentication. Basic SQL injection techniques can exploit this vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://projectworlds.in/
Restart Required: No
Instructions:
1. Check vendor website for updated version
2. Replace vulnerable login.php with patched version
3. Implement parameterized queries in all database interactions
4. Add input validation for all user-supplied parameters
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns in login.php requests
WAF-specific configuration commands
Input Validation Filter
allAdd server-side input validation to sanitize 'psd' parameter before processing
PHP: $psd = filter_var($_POST['psd'], FILTER_SANITIZE_STRING);
🧯 If You Can't Patch
- Isolate the Railway Reservation System behind a reverse proxy with strict input validation
- Implement network segmentation to restrict database access only to the application server
🔍 How to Verify
Check if Vulnerable:
Test login.php with SQL injection payloads in 'psd' parameter (e.g., ' OR '1'='1)Check Version:
Check application version in admin panel or source code commentsVerify Fix Applied:
Verify that SQL injection payloads no longer work and that parameterized queries are implemented📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts with SQL patterns
- Database connection errors
Network Indicators:
- HTTP POST requests to login.php containing SQL keywords
- Unusual database port traffic from web server
SIEM Query:
source="web_logs" AND uri="/login.php" AND (request_body CONTAINS "OR" OR request_body CONTAINS "UNION" OR request_body CONTAINS "SELECT")
