Description Preview

Syltek application versions prior to 10.22.00 contain a vulnerability related to insufficient verification of data authenticity (CWE-345). The application fails to properly validate that a product ID has a legitimate payment associated with it. This vulnerability allows attackers to forge requests that mark items as paid without actually completing any payment transaction, effectively bypassing the payment system entirely.

Overview

This vulnerability affects Syltek application versions before 10.22.00. The core issue stems from inadequate verification mechanisms when processing payment status for product IDs. The application does not properly authenticate or validate payment information before marking items as paid, creating a significant security gap in the payment workflow. An attacker with knowledge of the application's request structure could exploit this vulnerability to obtain products or services without making actual payments, resulting in financial loss for the organization implementing the Syltek application.

Remediation

Organizations using Syltek application should immediately upgrade to version 10.22.00 or later, which contains fixes for this vulnerability. If immediate upgrading is not possible, consider implementing additional security controls:

  • Monitor payment transactions for suspicious patterns
  • Implement additional verification layers for payment processing
  • Consider temporarily disabling online payment features if possible until the update can be applied
  • Review logs for evidence of exploitation

System administrators should also conduct a thorough review of past transactions to identify any potentially fraudulent activities that may have occurred due to this vulnerability.
