CVE-2023-48433
📋 TL;DR
CVE-2023-48433 allows unauthenticated attackers to execute arbitrary SQL commands against the Online Voting System Project v1.0 database through the username parameter in login_action.php. This affects all deployments of this specific voting system version that are exposed to network access. Attackers can manipulate database queries without needing valid credentials.
💻 Affected Systems
- Online Voting System Project
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including voter data theft, ballot manipulation, administrative account takeover, and potential remote code execution on the database server.
Likely Case
Database information disclosure (voter records, system credentials), authentication bypass, and data manipulation affecting election integrity.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages disclosure.
🎯 Exploit Status
SQL injection in login endpoints is commonly exploited. The advisory suggests multiple injection points exist.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://projectworlds.in/
Restart Required: No
Instructions:
No official patch available. Consider: 1. Replace with secure voting system 2. Manually implement parameterized queries in login_action.php 3. Add input validation for username parameter
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns in login requests
Input Validation Filter
linuxAdd PHP input validation before database queries
// Add to login_action.php before SQL execution
$username = mysqli_real_escape_string($connection, $_POST['username']);
// OR use prepared statements:
$stmt = $connection->prepare('SELECT * FROM users WHERE username = ?');
$stmt->bind_param('s', $_POST['username']);
🧯 If You Can't Patch
- Isolate the system behind strict network segmentation with no internet access
- Implement database-level protections: minimal privileges, query logging, and regular credential rotation
🔍 How to Verify
Check if Vulnerable:
Test login_action.php with SQL injection payloads like: username=admin' OR '1'='1Check Version:
Check PHP files for version comments or project documentationVerify Fix Applied:
Verify that SQL injection payloads no longer work and return generic error messages📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts with SQL syntax in username field
- Database error messages in application logs
- Unusual database queries from web server IP
Network Indicators:
- HTTP POST requests to login_action.php containing SQL keywords (UNION, SELECT, etc.)
- Abnormal response sizes from login endpoint
SIEM Query:
source="web_logs" AND uri="/login_action.php" AND (username="*UNION*" OR username="*SELECT*" OR username="*OR*'1'='1*")
