- python-ecdsa: DER encoding is not being verified in signatures (CVE-2019-14859)

- rubygem-activerecord-session_store: hijack sessions by using timing attacks targeting the session id (CVE-2019-25025)

- PyYAML: incomplete fix for CVE-2020-1747 (CVE-2020-14343)

- rubygem-nokogiri: XML external entity injection via Nokogiri::XML::Schema (CVE-2020-26247)

- rake: OS Command Injection via egrep in Rake::FileList (CVE-2020-8130)

- guava: local information disclosure via temporary directory created with unsafe permissions (CVE-2020-8908)

- Satellite: BMC controller credential leak via API (CVE-2021-20256)

- python-aiohttp: Open redirect in aiohttp.web_middlewares.normalize_path_middleware (CVE-2021-21330)

- rubygem-actionpack: Possible Information Disclosure / Unintended Method Execution in Action Pack (CVE-2021-22885)

- rails: Possible Denial of Service vulnerability in Action Dispatch (CVE-2021-22902)

- rails: Possible DoS Vulnerability in Action Controller Token Authentication (CVE-2021-22904)

- django: potential directory-traversal via uploaded files (CVE-2021-28658)

- rubygem-puma: incomplete fix for CVE-2019-16770 allows Denial of Service (DoS) (CVE-2021-29509)

How to Run

Here is how to run the RHEL 7 : Satellite 6.10 Release (Moderate) (RHSA-2021:4702) 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 Red Hat Local Security Checks plugin family.
  6. On the right side table select RHEL 7 : Satellite 6.10 Release (Moderate) (RHSA-2021:4702) plugin ID 155377.
  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 redhat-RHSA-2021-4702.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a redhat-RHSA-2021-4702.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - redhat-RHSA-2021-4702.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 redhat-RHSA-2021-4702.nasl -t <IP/HOST>

Go back to menu.
