SCA: security update for mitmproxy (GHSA-22gh-3r9q-xf38)

critical Tenable Cloud Security Plugin ID 408604

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- mitmproxy is an interactive, SSL/TLS-capable intercepting proxy. In mitmproxy 7.0.2 and below, a malicious
client or server is able to perform HTTP request smuggling attacks through mitmproxy. This means that a
malicious client/server could smuggle a request/response through mitmproxy as part of another
request/response's HTTP message body. While a smuggled request is still captured as part of another
request's body, it does not appear in the request list and does not go through the usual mitmproxy event
hooks, where users may have implemented custom access control checks or input sanitization. Unless one
uses mitmproxy to protect an HTTP/1 service, no action is required. The vulnerability has been fixed in
mitmproxy 7.0.3 and above. (CVE-2021-39214)
