CVE-2024-33962
📋 TL;DR
This CVE describes a critical SQL injection vulnerability in a payment module, allowing attackers to execute arbitrary SQL queries via a crafted 'code' parameter in an admin script. It affects version 1.0 of the software, potentially compromising sensitive payment data like credit card details. Organizations using the vulnerable version are at risk of data breaches.
💻 Affected Systems
- PayPal, Credit Card and Debit Card Payment module (likely part of a larger software suite, e.g., Janobe products)
📦 What is this software?
Paypal by Janobe
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the database, leading to theft of all stored payment information (e.g., credit card numbers, personal data), unauthorized transactions, and potential legal/financial penalties.
Likely Case
Data exfiltration of sensitive payment records, enabling fraud or identity theft, and possible disruption of payment processing functionality.
If Mitigated
Limited impact if input validation and parameterized queries are enforced, but residual risk may exist from other attack vectors.
🎯 Exploit Status
Exploitation involves sending crafted queries to the '/admin/mod_reservation/index.php' parameter; no authentication is required, making it easy for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-janobe-products
Restart Required: No
Instructions:
1. Check the vendor advisory for updates or patches. 2. If no patch is available, consider upgrading to a newer version if exists. 3. Apply input validation and use parameterized queries in the code.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation to sanitize the 'code' parameter, rejecting malicious SQL characters.
Not applicable; requires code changes in the PHP script.
Web Application Firewall (WAF) Rule
allDeploy a WAF to block SQL injection attempts targeting the vulnerable endpoint.
Not applicable; configure WAF rules via management interface.
🧯 If You Can't Patch
- Disable or restrict access to the '/admin/mod_reservation/index.php' script using network ACLs or authentication.
- Monitor logs for unusual SQL query patterns and implement intrusion detection systems.
🔍 How to Verify
Check if Vulnerable:
Review the software version and check if the vulnerable script exists; test with safe SQL injection probes (e.g., using tools like sqlmap in a controlled environment).Check Version:
Check the software documentation or configuration files for version information; no standard command provided.Verify Fix Applied:
After applying fixes, retest the endpoint to ensure SQL injection attempts are blocked and no data leakage occurs.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in server logs, especially with 'code' parameter containing SQL keywords like UNION, SELECT, or DROP.
Network Indicators:
- HTTP requests to '/admin/mod_reservation/index.php' with suspicious parameters indicative of SQL injection.
SIEM Query:
Example: 'source="web_server_logs" AND uri="/admin/mod_reservation/index.php" AND (param="code" AND value CONTAINS "' OR "1"="1")'
