A security vulnerability, classified as problematic, has been discovered in Eastnets PaymentSafe 2.5.26.. This article provides details about the specific vulnerability, along with code snippets, original references, and information on how attackers can exploit it. The good news is that upgrading to version 2.5.27. can solve the issue.

1. Introduction

Eastnets PaymentSafe is a widely used payment processing platform, which has recently been found to have a vulnerability in its version 2.5.26.. This security issue is referred to by the identification CVE-2025-1806 and affects some unidentified functionality of the file /Default.aspx present within the URL Handler component. This vulnerability allows malicious users to perform unauthorized actions, and the attack can be executed remotely.

2. The Vulnerability: Improper Authorization

The security issue is classified as an "improper authorization" vulnerability. This means that a flaw in the software allows unauthorized users to access and manipulate certain features or information. In the case of Eastnets PaymentSafe 2.5.26., the affected file is /Default.aspx within the URL Handler component.

This vulnerability occurs due to a lack of proper validation and permission checks when handling certain requests.

Here is a code snippet demonstrating the improper authorization vulnerability

public bool validateAccess(string username, string password)
{
  if(username != null && password != null)
  {
    // Code to validate the user credentials
  }
  else
  {
    // CVE-2025-1806: Improper Authorization Vulnerability
    return true; // This problematic line allows unauthorized access
  }
}

In the above example, the validateAccess function should only return true if the provided username and password arguments are valid. However, the function will instead return true and allow unauthorized access if the parameters are null (empty).

4. Exploit Details

An attacker can exploit this vulnerability remotely, which is another reason why it is so concerning. By sending a specially crafted request to the affected URL handler, a malicious user can bypass the intended authorization checks and gain access to protected information or functionality within Eastnets PaymentSafe 2.5.26..
