CVE-2022-32022

7.2 HIGH

📋 TL;DR

Car Rental Management System v1.0 contains a SQL injection vulnerability in the admin login endpoint that allows attackers to execute arbitrary SQL commands. This could lead to authentication bypass, data theft, or complete system compromise. Any organization using this specific software version is affected.

💻 Affected Systems

Products:
  • Car Rental Management System
Versions: v1.0
Operating Systems: Any OS running PHP web server
Default Config Vulnerable: ⚠️ Yes
Notes: Affects the default installation with no modifications. Requires PHP environment with database backend.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise including admin credential theft, data exfiltration, and potential remote code execution through database functions.

🟠

Likely Case

Authentication bypass leading to unauthorized admin access, followed by data manipulation or theft of sensitive customer information.

🟢

If Mitigated

Failed login attempts logged, no data access or system compromise due to proper input validation and parameterized queries.

🌐 Internet-Facing: HIGH - The vulnerable endpoint is accessible via web interface and requires no authentication.
🏢 Internal Only: MEDIUM - If system is only internally accessible, risk is reduced but still significant due to potential insider threats.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Public proof-of-concept available on GitHub. Exploitation requires basic SQL injection knowledge and web testing tools.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: None available

Restart Required: No

Instructions:

No official patch available. Consider migrating to alternative software or implementing custom fixes with parameterized queries.

🔧 Temporary Workarounds

Web Application Firewall (WAF) Rules

all

Implement WAF rules to block SQL injection patterns targeting the vulnerable endpoint

# Example ModSecurity rule: SecRule ARGS_GET:action "@rx login" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt blocked'"
# Add SQL injection detection patterns for the ajax.php endpoint

Input Validation Filter

linux

Add custom input validation to sanitize user inputs before processing

# PHP example: $action = filter_input(INPUT_GET, 'action', FILTER_SANITIZE_STRING);
# Validate and escape all user inputs before database queries

🧯 If You Can't Patch

  • Isolate the system behind a reverse proxy with strict input validation
  • Implement network segmentation to limit database access from web server

🔍 How to Verify

Check if Vulnerable:

Test the endpoint /ip/car-rental-management-system/admin/ajax.php?action=login with SQL injection payloads like ' OR '1'='1

Check Version:

Check software version in admin panel or readme files

Verify Fix Applied:

Attempt SQL injection attacks against the endpoint and verify they are blocked or properly handled

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL syntax in web server logs
  • Multiple failed login attempts with SQL patterns
  • Database error messages containing SQL fragments

Network Indicators:

  • HTTP requests to ajax.php with SQL keywords in parameters
  • Unusual database connection patterns from web server

SIEM Query:

source="web_logs" AND uri="*ajax.php*" AND (query="*OR*1*1*" OR query="*UNION*SELECT*" OR query="*--*" OR query="*;*" OR query="*'*'*'")
