When a web server returns the header Server: WSGIServer/0.2 CPython/3.10.4 , it reveals that the application is running on using a basic WSGI (Web Server Gateway Interface) server. In many cases, this specific version combination is associated with MkDocs 1.2.2 or older versions of Django used for local development. Key Vulnerabilities 1. Directory Traversal (CVE-2021-40978) Because WSGIServer/0
Patching to newer versions (e.g., Python 3.10.9 or later) resolves core library vulnerabilities like CVE-2021-28861 . In many cases, this specific version combination is
Security professionals use tools like nmap or curl to identify these servers: nmap -sV -p 8000
The server does not properly sanitize file paths, allowing attackers to request files outside the intended web root.
This can lead to information disclosure or be used in phishing attacks to redirect users to malicious domains. 3. Application-Level Command Injection
