An attacker sends a malformed HTTP request containing both headers.
An older, lightweight Python WSGI HTTP server designed for serving Python web applications. It lacks modern request filtering and security headers.
The combination of WSGIServer 02 and CPython 3.10.4 introduces distinct attack surfaces. The most common exploitation vectors include: HTTP Request Smuggling
POST / HTTP/1.1 Host: vulnerable-target.com Content-Length: 44 Transfer-Encoding: chunked 0 GET /admin/delete-user HTTP/1.1 Host: localhost Use code with caution. Scenario B: Exploiting Pickle Deserialization
Older WSGI server iterations occasionally mishandle URL decoding.
Web Server Gateway Interface (WSGI) servers are critical components in the Python web ecosystem. They bridge the gap between web servers and Python web applications. However, using outdated server software like alongside specific runtime environments like CPython 3.10.4 can expose systems to severe security risks.
WSGIServer 02 fails to strictly validate the Content-Length and Transfer-Encoding headers.
If the WSGI application parses cookies unsafely using an older Python 3.10.4 library, an attacker extracts system files using a serialized object:
