Attention all users and administrators of Bluestar Micro Mall 1.! A critical vulnerability has been uncovered and classified as CVE-2025-2952. This high-risk security issue has the potential to compromise the integrity of your system due to a lack of effective controls on file uploads, leading to unrestricted file upload attacks. In this detailed long-read, we will outline the vulnerable component, delve into the technical details of the exploit, provide a code snippet for understanding, and link to original sources and references to help you protect your system.

Vulnerable Component

The point of vulnerability within Bluestar Micro Mall 1. is an unknown functionality present in the file /api/api.php?mod=upload&type=1. When exploited, it allows for unfettered access to upload files to the target system. This malicious tactic can lead to a variety of dangerous attacks including remote code execution, data breaches, and even complete system compromise.

Technical Details of the Exploit

The key to this exploit lies in the manipulation of the argument File, which is not properly sanitized or validated. Attackers can manipulate this argument in order to upload any file, regardless of its type or content, ultimately granting them the ability to execute malicious code on the vulnerable system.

Code Snippet

To illustrate the vulnerability, the following code snippet demonstrates how the exploit can be executed:

import requests

url = "http://target/vulnerable_api_link.php";
payload = {'mod': 'upload', 'type': '1'}

file_to_upload = {'File': ('vulnerable_code.php', open('vulnerable_code.php', 'rb'))}
response = requests.post(url, data=payload, files=file_to_upload)

if response.status_code == 200:
    print("File uploaded successfully!")
else:
    print("Error during file upload.")

This code snippet, written in Python, takes advantage of the requests library to issue a POST request containing the manipulated File argument. The attackers can easily modify the vulnerable_code.php file to contain any malicious code or content they desire, thereby gaining unauthorized access to your system.

Conclusion and Recommendations

In order to protect your system from this critical vulnerability, it is essential to apply proper input validation and sanitization on the File argument within the /api/api.php?mod=upload&type=1 functionality. Additionally, consider implementing a white-list approach for allowed file types in order to further strengthen security measures and mitigate potential attacks.

Stay informed and be proactive in managing your system's security. Promptly apply necessary updates, patches, and code modifications to safeguard your valuable data and resources from potential exploiting. Stay vigilant and stay secure!
