Echo: requests: security update to 2.28.1+dfsg-1-e1

medium Tenable Cloud Security Plugin ID 458990

Description

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

 - Requests is a HTTP library. Since Requests 2.3.0, Requests has been leaking Proxy-Authorization headers to
 destination servers when redirected to an HTTPS endpoint. This is a product of how we use
 `rebuild_proxies` to reattach the `Proxy-Authorization` header to requests. For HTTP connections sent
 through the tunnel, the proxy will identify the header in the request itself and remove it prior to
 forwarding to the destination server. However when sent over HTTPS, the `Proxy-Authorization` header must
 be sent in the CONNECT request as the proxy has no visibility into the tunneled request. This results in
 Requests forwarding proxy credentials to the destination server unintentionally, allowing a malicious
 actor to potentially exfiltrate sensitive information. This issue has been patched in version 2.31.0.
 (CVE-2023-32681)

Solution

Update the requests library and its related packages to version 2.28.1+dfsg-1-e1 or later.
