Python Exposure Detection Scanner

The Python programming language is widely used by developers and data scientists to create software applications, data analysis scripts, and web applications. Python is chosen for its readability, simplicity, and a wide range of available libraries. It is commonly used in academic settings for research purposes as well as in industries like technology, finance, and healthcare for various applications. The "setup.py" file is a standard file used to specify metadata about a Python package, including its dependencies, to aid in the package installation and distribution process. When "setup.py" files are exposed on the internet, they can reveal critical information such as package names and dependencies, which may assist attackers in finding potential entry points. Ensuring the security of such files is crucial to protecting software integrity and minimizing risks.

The exposure vulnerability detected by this scanner pertains to the unintentional exposure of Python 'setup.py' files. These files are part of Python packages and often contain metadata about the package, including name, version, author, and dependencies. An exposed 'setup.py' file could allow malicious actors to gather information about the software package's setup and dependencies. This information might aid attackers in crafting further targeted attacks, especially if critical or sensitive metadata is included. It's essential to ensure that such files are not inadvertently exposed to untrusted parties.

The technical details of this vulnerability include the detection of the 'setup.py' file being accessible via URLs on web servers. The scanning process looks for key indicators within the file contents, such as 'import os', 'find_packages', and the 'setup(' function call, which are commonly found in 'setup.py' files. Additionally, the scanner checks the content type to confirm it matches Python-related files or scripts. Ensuring the file is not publicly accessible is a fundamental measure to mitigate this risk.

Possible effects of exploiting this vulnerability include unauthorized access to detailed technical information about a Python package. Attackers could use this information to locate and exploit dependencies, leading to potential security breaches. Further, if any hardcoded credentials or tokens exist within the 'setup.py', there is a risk of unauthorized access to specific services used by the application.
