CVE-2026-3711
📋 TL;DR
This SQL injection vulnerability in Simple Flight Ticket Booking System 1.0 allows attackers to execute arbitrary SQL commands through the /Adminupdate.php endpoint. Remote attackers can potentially access, modify, or delete database content. All deployments of version 1.0 are affected.
💻 Affected Systems
- Simple Flight Ticket Booking System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including sensitive data exfiltration, authentication bypass, or full system takeover
Likely Case
Data theft or manipulation of flight booking records, potentially leading to financial loss or service disruption
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-critical data
🎯 Exploit Status
Public exploit details available; SQL injection is well-understood and easily weaponized
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement parameterized queries and input validation for all user-supplied parameters in /Adminupdate.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('UPDATE flights SET flightno=?, airplaneid=?, departure=?, dtime=?, arrival=?, atime=?, ec=?, ep=?, bc=?, bp=? WHERE id=?'); $stmt->bind_param('ssssssssssi', $flightno, $airplaneid, $departure, $dtime, $arrival, $atime, $ec, $ep, $bc, $bp, $id);
Web Application Firewall Rules
allBlock SQL injection patterns targeting the vulnerable parameters
Add WAF rule: SecRule ARGS_NAMES "^(flightno|airplaneid|departure|dtime|arrival|atime|ec|ep|bc|bp)$" "phase:2,deny,status:403,id:1001,msg:'SQLi attempt detected'"
ModSecurity rule: SecRule REQUEST_URI "@contains /Adminupdate.php" "chain,phase:2,deny,status:403,id:1002,msg:'Blocking SQLi attempt'" SecRule ARGS "@detectSQLi"
🧯 If You Can't Patch
- Block external access to /Adminupdate.php using firewall rules or web server configuration
- Implement database user with minimal permissions (read-only where possible) and enable logging of all database queries
🔍 How to Verify
Check if Vulnerable:
Test /Adminupdate.php endpoint with SQL injection payloads in flightno, airplaneid, departure, dtime, arrival, atime, ec, ep, bc, or bp parametersCheck Version:
Check source code or documentation for version 1.0 referencesVerify Fix Applied:
Attempt SQL injection after implementing parameterized queries and verify error responses don't reveal database information📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web logs
- Multiple failed parameter validation attempts on /Adminupdate.php
- Database queries with unusual syntax or UNION statements
Network Indicators:
- HTTP POST requests to /Adminupdate.php with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/Adminupdate.php" AND (param="*UNION*" OR param="*SELECT*" OR param="*INSERT*" OR param="*DELETE*" OR param="*UPDATE*")
