Overview
A serious security vulnerability, identified as CVE-2025-29017, has been detected in the Code Astro Internet Banking System 2.0.0. This flaw allows malicious actors to execute arbitrary code remotely on the affected systems. The vulnerability arises due to improper validation of file uploads in the profile_pic parameter within pages_view_client.php. This vulnerability affects all users of the Code Astro Internet Banking System 2.0.0 and can lead to system compromise or data leakage. It highlights the broader issue of the need for rigorous security practices in the development of internet banking systems.

Affected Products
Product | Affected Versions
Code Astro Internet Banking System | 2.0.0
How the Exploit Works
The vulnerability is triggered when a malicious actor uploads a file through the profile_pic parameter in pages_view_client.php. The system does not perform appropriate validation checks on the uploaded file, allowing an attacker to upload and execute arbitrary code. This can lead to unauthorized access to the system, potentially compromising the system or leading to data leakage.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited. This is a pseudocode representation of a malicious file upload:
POST /pages_view_client.php HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="profile_pic"; filename="malicious.jpg"
Content-Type: image/jpeg
{ "malicious_code": "..." }
------WebKitFormBoundary7MA4YWxkTrZu0gW--In this example, a malicious file named “malicious.jpg” is uploaded as a profile picture. The malicious code embedded in the file is executed once the file is processed by the server.
Mitigation
To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure to block malicious file uploads. It is also essential for organizations to foster a security culture that emphasizes the importance of secure coding practices to prevent such vulnerabilities in the future.
