CVE-2023-44166
📋 TL;DR
This is a SQL injection vulnerability in the 'age' parameter of process_registration.php that allows attackers to execute arbitrary SQL commands on the database. Any system running the vulnerable software with this endpoint exposed is affected, potentially leading to complete database compromise.
💻 Affected Systems
- ProjectWorlds.in software with process_registration.php
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full database compromise including data theft, data manipulation, privilege escalation, and potential remote code execution on the database server.
Likely Case
Data exfiltration, authentication bypass, and unauthorized access to sensitive user information stored in the database.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
SQL injection vulnerabilities are commonly weaponized and this appears to be a straightforward parameter manipulation attack.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown specific version - check vendor advisory
Vendor Advisory: https://projectworlds.in/
Restart Required: No
Instructions:
1. Download latest version from vendor. 2. Replace vulnerable process_registration.php. 3. Implement parameterized queries. 4. Add input validation for age parameter.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to only accept numeric values for age parameter
Add to process_registration.php: if(!is_numeric($_POST['age'])) { die('Invalid input'); }
WAF Rule
allBlock SQL injection patterns in age parameter
Configure WAF to block patterns like UNION, SELECT, INSERT, DELETE, DROP in age parameter
🧯 If You Can't Patch
- Implement web application firewall with SQL injection rules
- Disable or restrict access to process_registration.php endpoint
🔍 How to Verify
Check if Vulnerable:
Test age parameter with SQL injection payload: age=1' OR '1'='1Check Version:
Check PHP file modification date and compare with vendor's patched versionVerify Fix Applied:
Test with same payload - should receive error or rejection instead of successful SQL execution📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed registration attempts with SQL syntax
- Age parameter containing SQL keywords
Network Indicators:
- HTTP POST requests to process_registration.php with SQL injection patterns in age parameter
SIEM Query:
source="web_logs" AND uri="/process_registration.php" AND (age="*UNION*" OR age="*SELECT*" OR age="*INSERT*")
