CVE-2020-18716

9.8 CRITICAL

📋 TL;DR

CVE-2020-18716 is a critical SQL injection vulnerability in Rockoa v1.8.7 that allows remote attackers to execute arbitrary SQL commands through insufficient parameter filtering in wordAction.php. This enables attackers to gain administrative privileges, access sensitive data, or compromise the entire database. All organizations running Rockoa v1.8.7 are affected.

💻 Affected Systems

Products:
  • Rockoa
Versions: v1.8.7
Operating Systems: All operating systems running PHP
Default Config Vulnerable: ⚠️ Yes
Notes: Any Rockoa installation using the default configuration with wordAction.php accessible is vulnerable.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise including database takeover, data exfiltration, privilege escalation to admin, and potential lateral movement to other systems.

🟠

Likely Case

Attackers gain administrative access to the Rockoa application, steal sensitive business data, and potentially execute arbitrary commands on the database server.

🟢

If Mitigated

Limited impact with proper input validation, parameterized queries, and web application firewall rules blocking SQL injection patterns.

🌐 Internet-Facing: HIGH - The vulnerability is remotely exploitable without authentication, making internet-facing instances immediate targets.
🏢 Internal Only: HIGH - Even internal instances are vulnerable to insider threats or attackers who breach the network perimeter.

🎯 Exploit Status

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

SQL injection vulnerabilities are commonly weaponized, and this specific vulnerability has public proof-of-concept available.

🛠️ 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 wordAction.php file with the patched version. 4. Verify the fix by testing parameter inputs.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement strict input validation for all parameters passed to wordAction.php

Modify wordAction.php to add parameter sanitization: $param = mysqli_real_escape_string($connection, $_GET['param']);

WAF Rule Implementation

all

Deploy web application firewall rules to block SQL injection patterns

Add WAF rule: SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"

🧯 If You Can't Patch

  • Implement network segmentation to isolate Rockoa from critical systems
  • Deploy a web application firewall with SQL injection detection rules

🔍 How to Verify

Check if Vulnerable:

Check if your Rockoa installation is version 1.8.7 and examine wordAction.php for proper parameter filtering

Check Version:

Check Rockoa version in admin panel or examine version files in installation directory

Verify Fix Applied:

Test parameter inputs with SQL injection payloads (e.g., ' OR '1'='1) and verify they are properly sanitized or rejected

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in database logs
  • Multiple failed login attempts from wordAction.php
  • Suspicious parameter values containing SQL keywords

Network Indicators:

  • HTTP requests to wordAction.php with SQL injection patterns
  • Unusual database connection patterns from web server

SIEM Query:

source="web_logs" AND uri="*wordAction.php*" AND (param="*' OR*" OR param="*UNION SELECT*" OR param="*DROP TABLE*")
