Notes: Affects all installations of version 1.0 regardless of configuration. The vulnerability exists in the core application code.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise including data theft, data manipulation, authentication bypass, and potential remote code execution via database functions.

🟠

Likely Case

Unauthorized data access, extraction of sensitive client information, and potential privilege escalation within the database.

🟢

If Mitigated

Limited impact with proper input validation and parameterized queries preventing successful injection.

🌐 Internet-Facing: HIGH - The vulnerable endpoint is accessible via POST requests, making internet-facing installations immediately exploitable.
🏢 Internal Only: HIGH - Even internal systems are vulnerable to authenticated or unauthenticated attacks depending on access controls.

🎯 Exploit Status

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

SQL injection via POST parameter requires minimal technical skill. Public GitHub repository contains exploit details.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: None available

Restart Required: No

Instructions:

No official patch available. Consider upgrading to a newer version if available, or implement workarounds.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Add server-side validation to ensure order_id contains only expected characters (numbers)

Modify user_payment_update.php to validate order_id parameter using preg_match('/^\d+$/', $_POST['order_id'])

Parameterized Query Implementation

all

Replace direct SQL concatenation with prepared statements using PDO or mysqli

Replace $sql = "UPDATE payments SET ... WHERE order_id = '".$_POST['order_id']."'" with prepared statement: $stmt = $pdo->prepare("UPDATE payments SET ... WHERE order_id = ?"); $stmt->execute([$_POST['order_id']]);

🧯 If You Can't Patch

  • Implement web application firewall (WAF) rules to block SQL injection patterns in POST parameters
  • Restrict network access to the application using firewall rules, allowing only trusted IP addresses

🔍 How to Verify

Check if Vulnerable:

Test by sending a POST request to user_payment_update.php with order_id parameter containing SQL injection payload like ' OR '1'='1

Check Version:

Check application version in admin panel or review source code comments for version information

Verify Fix Applied:

Attempt the same SQL injection test after implementing fixes - should receive error or no database modification

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL error messages in application logs
  • Multiple failed payment update attempts with malformed order_id values
  • Database queries containing UNION, SELECT, or other SQL keywords from unexpected sources

Network Indicators:

  • POST requests to user_payment_update.php containing SQL keywords in parameters
  • Unusual database connection patterns from web server

SIEM Query:

source="web_logs" AND uri="/user_payment_update.php" AND (param="order_id" AND value MATCHES "'.*OR.*|UNION|SELECT.*FROM")
