Description

This security bulletin contains information about 1 vulnerability.


1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2020-28473)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to the usage of a vector called parameter cloaking. A remote attacker can trick the victim into opening a specially crafted HTTP request, smuggle arbitrary HTTP headers and cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server.
