CVE-2020-18714
📋 TL;DR
CVE-2020-18714 is a critical SQL injection vulnerability in Rockoa v1.8.7 that allows remote attackers to execute arbitrary SQL commands through the wordModel.php file. This can lead to privilege escalation, data theft, or complete system compromise. All organizations running Rockoa v1.8.7 are affected.
💻 Affected Systems
- Rockoa
📦 What is this software?
Rockoa by Rockoa
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover: attackers can execute arbitrary SQL commands to steal all database data, create administrative accounts, or execute operating system commands if database permissions allow.
Likely Case
Data breach and privilege escalation: attackers typically extract sensitive data (user credentials, personal information) and gain administrative access to the application.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, restricting attackers to read-only database access.
🎯 Exploit Status
SQL injection vulnerabilities are well-understood and easily weaponized. Public exploit details are available in vulnerability databases.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.8.8 or later
Vendor Advisory: https://github.com/rockoa/rockoa/releases
Restart Required: No
Instructions:
1. Backup your current Rockoa installation and database. 2. Download the latest version from the official repository. 3. Replace the vulnerable wordModel.php file with the patched version. 4. Verify the fix by testing the affected functionality.
🔧 Temporary Workarounds
Input Validation Filter
allAdd strict input validation to filter SQL injection patterns in wordModel.php
# Edit wordModel.php and add parameter validation before SQL execution
# Example: if(preg_match('/[^a-zA-Z0-9_]/', $input)) { die('Invalid input'); }
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules
# For ModSecurity: SecRule ARGS "@detectSQLi" "id:1000,phase:2,deny"
🧯 If You Can't Patch
- Immediately isolate the Rockoa server from internet access and restrict internal network access
- Implement strict network segmentation and monitor all database queries from the Rockoa application
🔍 How to Verify
Check if Vulnerable:
Check if your Rockoa installation is version 1.8.7 by examining the version file or checking the application interfaceCheck Version:
grep -r 'version' rockoa_directory/ or check admin panelVerify Fix Applied:
Test the getdata function in wordModel.php with SQL injection payloads to ensure they are properly rejected📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts followed by successful admin access
- SQL syntax errors in application logs
Network Indicators:
- Unusual database connection patterns from web server
- SQL injection patterns in HTTP requests to wordModel.php
SIEM Query:
source="web_logs" AND (url="*wordModel.php*" AND (method="POST" OR method="GET") AND (content="*UNION*" OR content="*SELECT*" OR content="*INSERT*" OR content="*DELETE*"))
