📦 What is this software?
Shutterstock Clone by Shutterstock Clone Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, authentication bypass, and potential remote code execution if database permissions allow.
Likely Case
Database information disclosure, data manipulation, and potential privilege escalation leading to administrative access.
If Mitigated
Limited impact with proper input validation and parameterized queries in place, potentially preventing successful exploitation.
🎯 Exploit Status
Multiple public exploit scripts available. Exploitation requires no authentication and uses simple SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
1. Check vendor website for updated version
2. If no patch available, implement workarounds
3. Consider replacing with alternative software
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for the keywords parameter to only allow alphanumeric characters
Modify PHP code to add: if (!preg_match('/^[a-zA-Z0-9\s]+$/', $_GET['keywords'])) { die('Invalid input'); }
Parameterized Queries
allReplace direct SQL concatenation with prepared statements using PDO or mysqli
Replace: $sql = "SELECT * FROM table WHERE keywords = '" . $_GET['keywords'] . "'";
With: $stmt = $pdo->prepare("SELECT * FROM table WHERE keywords = ?");
$stmt->execute([$_GET['keywords']]);
🧯 If You Can't Patch
- Implement WAF rules to block SQL injection patterns in the keywords parameter
- Restrict access to the vulnerable endpoint using IP whitelisting or authentication
🔍 How to Verify
Check if Vulnerable:
Test the /Category endpoint with SQL injection payloads like: ' OR '1'='1Check Version:
Check software version in admin panel or readme filesVerify Fix Applied:
Test with same payloads after implementing fixes - should return error or no data📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in logs
- Multiple failed login attempts after SQL injection
- Long or unusual parameter values in access logs
Network Indicators:
- HTTP requests with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
web_access_logs | where url contains "/Category" and (parameter contains "' OR" or parameter contains "UNION" or parameter contains "SELECT" or parameter contains "--")
