Astra Linux – Vulnerability in Waitress

Waitress version 1.3.1 allows for the smuggling of requests by sending the Content-Length header twice. Waitress would fold the two Content-Length headers together, and since it cannot convert the now comma-separated values into integers, it internally sets the Content-Length to 0. If two...
