Background

pyload-ng is a Python package available on PyPI that provides a download manager for various file hosting websites. It is designed to be a lightweight and efficient tool for managing downloads. However, a code injection vulnerability has been discovered in versions prior to 0.5.0b3.dev31. This vulnerability allows an attacker to execute arbitrary code on the server hosting pyload-ng, potentially leading to remote code execution and unauthorized access to sensitive data.

Vulnerability Detail

The code injection vulnerability in pyload-ng arises from improper input validation and sanitization. An attacker can exploit this vulnerability by injecting malicious code into user-supplied input, such as URLs or filenames. When this input is processed by pyload-ng, the injected code is executed within the context of the application, enabling the attacker to execute arbitrary commands and potentially gain control over the server. This vulnerability poses a significant risk to the confidentiality, integrity, and availability of the affected system.

pip install --upgrade "pyload-ng==0.5.0b3.dev101"

pip install --upgrade "pyload-ng==0.5.0b3.dev31"

Workaround

As a temporary workaround, users can implement input validation and sanitization measures within their own code to mitigate the risk of code injection. It is crucial to thoroughly validate and sanitize any user-supplied input before processing it with pyload-ng. This can be achieved by using appropriate input validation libraries or implementing custom validation logic. Here is an example of input validation using the requests library:

import requests

url = input('Enter URL: ')

Validate and sanitize input

if not url.startswith('http://') and not url.startswith('https://'): print('Invalid URL') exit()

Process the validated input

response = requests.get(url)

Continue with pyload-ng operations

Conclusion

The code injection vulnerability in pyload-ng prior to version 0.5.0b3.dev31 poses a significant risk to the security of the affected systems. It is crucial to update to the latest version to mitigate this vulnerability. Failure to do so may result in remote code execution and unauthorized access to sensitive data.
