HTTP Package Retrieval Vulnerability in Setuptools by Python Software Foundation

CVE-2013-1633

What is CVE-2013-1633?

Setuptools, a package development and distribution library for Python, has a vulnerability that allows man-in-the-middle attackers to execute arbitrary code. This occurs because easy_install in versions prior to 0.7 retrieves packages via HTTP and does not verify the integrity of the package contents. Attackers could potentially exploit this by intercepting the HTTP response to inject malicious code during the package retrieval process. It is crucial for developers to update to safer versions and utilize secure methods to manage packages.
