CVE-2024-44812
📋 TL;DR
This SQL injection vulnerability in Online Complaint Site v1.0 allows remote attackers to execute arbitrary SQL commands via the username and password parameters in the admin login component. Attackers can bypass authentication, escalate privileges, and potentially gain full control of the application. All deployments of Online Complaint Site v1.0 are affected.
💻 Affected Systems
- Online Complaint Site
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the application database leading to data theft, privilege escalation to admin, and potential remote code execution on the underlying server.
Likely Case
Authentication bypass allowing attackers to gain administrative access to the complaint management system and manipulate complaint data.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
Public proof-of-concept code is available on GitHub. The exploit requires no authentication and uses simple SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check for official patch from vendor
2. If no patch available, implement workarounds
3. Consider migrating to alternative software
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for all user inputs
// PHP example using prepared statements:
$stmt = $conn->prepare('SELECT * FROM users WHERE username = ? AND password = ?');
$stmt->bind_param('ss', $username, $password);
$stmt->execute();
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection attempts
# ModSecurity example rule:
SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
🧯 If You Can't Patch
- Implement network segmentation to restrict access to the admin interface
- Deploy a web application firewall with SQL injection detection rules
🔍 How to Verify
Check if Vulnerable:
Test the admin login page with SQL injection payloads like ' OR '1'='1 in username/password fieldsCheck Version:
Check the software version in the footer or about page, or examine source code files for version markersVerify Fix Applied:
Attempt SQL injection attacks after implementing fixes and verify they are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in login attempts
- Multiple failed login attempts with SQL keywords
- Successful admin logins from unexpected IPs
Network Indicators:
- HTTP POST requests to /admin.index.php containing SQL keywords
- Unusual database query patterns
SIEM Query:
source="web_logs" AND (url="/admin.index.php" AND (request_body CONTAINS "' OR" OR request_body CONTAINS "UNION" OR request_body CONTAINS "SELECT *"))
