    # Standard user gains access to the BRAIN2 configuration file
    config_file = open('C:\\Program Files\\BRAIN2\\config_file.cfg')
    # Reads encrypted database access data
    encrypted_data = config_file.read()
    # User uses a decryption algorithm to decrypt the data
    decrypted_data = decryption_algorithm(encrypted_data)
    # User now has access to sensitive database information
    print(decrypted_data)
    # Possible system compromise or data leakage
    compromise_system_or_leak_data(decrypted_data)

    Mitigation Guidance

    To mitigate this vulnerability, the recommended approach is to apply the vendor patch as soon as it becomes available. This patch should address the vulnerability and eliminate the risk it poses.

    Content-Type: application/json
    {
    "report": {
    "title": "Quarterly Financial Report",
    "data": "...",
    "script": "<script>malicious_code_here</script>"
    }
    }

    In this example, the “malicious_code_here” would be replaced by the specific actions the attacker wants to perform with admin privileges on the server.

    Mitigation and Prevention

    The most effective mitigation for this vulnerability is to apply the vendor patch. If this is not immediately possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help provide temporary mitigation. These tools can potentially detect and block attempts to exploit this vulnerability. However, they should not be seen as a long-term solution, and applying the vendor patch should be prioritized.

    Affected Products

    Product | Affected Versions

    Innoshop | Up to and including 0.4.1

    How the Exploit Works

    An authenticated attacker can exploit this vulnerability by manipulating the File Manager functions in the admin panel. Initially, the attacker would upload a crafted file. The application checks if the uploaded files are image files; however, this check can be bypassed by simply renaming the uploaded file to have a .php extension using the Rename Function.
    This bypass is possible due to the application only relying on frontend checks to restrict the administrator from changing the extension of uploaded files to .php. This restriction can be easily bypassed using any proxy tool, such as BurpSuite. Once the attacker renames the file and gives it the .php extension, a GET request can be used to trigger the execution of code on the server.

    Conceptual Example Code

    Below is a conceptual example of how the vulnerability might be exploited. This represents the HTTP request made to rename the uploaded file to a .php extension.

    GET /admin/file_manager/rename?old_filename=attack.jpg&new_filename=attack.php HTTP/1.1
    Host: target.example.com
    Authorization: Bearer [User's Authenticated JWT]

    Now, with the file renamed to a .php extension, the attacker can trigger the execution of the code on the server with the following GET request:

    GET /uploads/attack.php HTTP/1.1
    Host: target.example.com

    Please note that the above is only a conceptual representation and the actual exploit may vary based on the specific environment and conditions.

    Mitigation Guidance

    To mitigate the threat from this vulnerability, it is advised to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure.
