The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1916 advisory.
pip is a package management system used to install and manage software packages written in Python. Many packages can be found in the Python Package Index (PyPI). pip is a recursive acronym that can stand for either Pip Installs Packages or Pip Installs Python.
Security Fix(es):
* python-urllib3: Cross-host redirect does not remove Authorization header allow for credential exposure (CVE-2018-20060)
* python-urllib3: CRLF injection due to not encoding the '\r\n' sequence leading to possible attack on internal service (CVE-2019-11236)
* python-urllib3: Certification mishandle when error should be thrown (CVE-2019-11324)
* python-requests: Redirect from HTTPS to HTTP does not remove Authorization header (CVE-2018-18074)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Additional Changes:
For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.2 Release Notes linked from the References section.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
