CVE-2023-36213

9.8 CRITICAL

📋 TL;DR

This SQL injection vulnerability in MotoCMS v3.4.3 allows remote attackers to execute arbitrary SQL commands via the keyword parameter in the search function. Attackers can gain administrative privileges, access sensitive data, or compromise the entire database. All websites running MotoCMS v3.4.3 with the vulnerable search functionality are affected.

💻 Affected Systems

Products:
  • MotoCMS
Versions: 3.4.3
Operating Systems: All
Default Config Vulnerable: ⚠️ Yes
Notes: Any MotoCMS 3.4.3 installation with the search functionality enabled is vulnerable. The vulnerability is in the core CMS code.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise: attacker gains administrative access, exfiltrates all database content (including user credentials, payment info), executes arbitrary code on the server, and potentially pivots to other systems.

🟠

Likely Case

Privilege escalation to admin, data theft of user information and site content, and potential website defacement or data destruction.

🟢

If Mitigated

Attack attempts are blocked at the WAF level, SQL injection fails due to parameterized queries, and only error logs show attempted exploitation.

🌐 Internet-Facing: HIGH - The search function is typically internet-facing and accessible to unauthenticated users, making exploitation trivial from anywhere.
🏢 Internal Only: MEDIUM - If the application is only accessible internally, risk is reduced but still significant if internal users can exploit it.

🎯 Exploit Status

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

Public exploit code is available on Exploit-DB and Packet Storm. Exploitation requires minimal technical skill as it's a straightforward SQL injection.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: Not available

Restart Required: No

Instructions:

1. Check MotoCMS vendor website for security updates. 2. If no patch is available, upgrade to the latest version if it addresses the vulnerability. 3. Apply workarounds immediately.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Implement strict input validation for the keyword parameter to reject SQL special characters.

Modify search.php to add: $keyword = preg_replace('/[^a-zA-Z0-9\s]/', '', $_GET['keyword']);

WAF Rule Implementation

all

Deploy web application firewall rules to block SQL injection patterns in search parameters.

ModSecurity rule: SecRule ARGS:keyword "@detectSQLi" "id:1001,phase:2,deny,status:403"

🧯 If You Can't Patch

  • Disable the search functionality completely if not essential
  • Implement network segmentation to isolate the MotoCMS server and restrict database access

🔍 How to Verify

Check if Vulnerable:

Test the search function with SQL injection payloads like: keyword=test' OR '1'='1

Check Version:

Check MotoCMS admin panel or read version.txt in the installation directory

Verify Fix Applied:

Attempt SQL injection tests and verify they are blocked or sanitized without affecting legitimate searches

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL errors in application logs
  • Multiple search requests with SQL special characters
  • Admin login attempts from unusual IPs

Network Indicators:

  • HTTP requests with SQL keywords in search parameters
  • Unexpected database connection patterns

SIEM Query:

source="web_logs" AND (uri_path="/search" AND query_string="*keyword=*'*" OR query_string="*keyword=*%27*")
