  script_set_attribute(attribute:"description", value:
"According to the versions of the python-pip packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :

  - urllib3 before 1.24.2 does not remove the authorization HTTP header when following a cross-origin redirect
    (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the
    authorization header to be exposed to unintended hosts or transmitted in cleartext. NOTE: this issue
    exists because of an incomplete fix for CVE-2018-20060 (which was case-sensitive). (CVE-2018-25091)

  - urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header
    special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user.
    However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP
    redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been
    patched in urllib3 version 1.26.17 or 2.0.5. (CVE-2023-43804)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
