Synopsis

The remote CentOS host is missing one or more security updates.

Description

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2021:4162 advisory.

- python-psutil: Double free because of refcount mishandling (CVE-2019-18874)

- python-jinja2: ReDoS vulnerability in the urlize filter (CVE-2020-28493)

- CVE-2021-42771 python-babel: Relative path traversal allows attacker to load arbitrary locale files and execute arbitrary code (CVE-2021-20095)

- python: Web cache poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a semicolon in query parameters (CVE-2021-23336)

- python-lxml: Missing input sanitization for formaction HTML5 attributes may lead to XSS (CVE-2021-28957)

- python-ipaddress: Improper input validation of octal strings (CVE-2021-29921)

- python-urllib3: ReDoS in the parsing of authority part of URL (CVE-2021-33503)

- python: Information disclosure via pydoc (CVE-2021-3426)

- python-pip: Incorrect handling of unicode separators in git references (CVE-2021-3572)

- CVE-2021-20095 python-babel: Relative path traversal allows attacker to load arbitrary locale files and execute arbitrary code (CVE-2021-42771)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.

How to Run

Here is how to run the CentOS 8 : python38:3.8 and python38-devel:3.8 (CESA-2021:4162) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

  1. Click to start a New Scan.
  2. Select Advanced Scan.
  3. Navigate to the Plugins tab.
  4. On the top right corner click to Disable All plugins.
  5. On the left side table select CentOS Local Security Checks plugin family.
  6. On the right side table select CentOS 8 : python38:3.8 and python38-devel:3.8 (CESA-2021:4162) plugin ID 155064.
  7. Specify the target on the Settings tab and click to Save the scan.
  8. Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl centos8_RHSA-2021-4162.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a centos8_RHSA-2021-4162.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - centos8_RHSA-2021-4162.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state centos8_RHSA-2021-4162.nasl -t <IP/HOST>

Go back to menu.
