The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:4591 advisory.

    Red Hat Update Infrastructure (RHUI) offers a highly scalable, highly redundant framework that enables you     to manage repositories and content. It also enables cloud providers to deliver content and updates to Red     Hat Enterprise Linux (RHEL) instances.

    Security Fix(es):
    * Django: Potential bypass of validation when uploading multiple files using a single form field     (CVE-2023-31047)

    * sqlparse: Parser contains a regular expression that is vulnerable to ReDOS (Regular Expression Denial of     Service) (CVE-2023-30608)

    This RHUI update fixes the following bugs:

    * Previously, the `rhui-manager` command used the `logname` command to obtain the login name. However,     when `rhui-manager` is run using the `rhui-repo-sync` cron job, a login name is not defined. Consequently,     emails sent by the cron job contained the error message `logname: no login name`. With this update, `rhui-     manager` does not obtain the login name using the `logname` command and the error message is no longer     generated.

    * Previously, when an invalid repository ID was used with the `rhui-manager` command to synchronize or     delete a repository, the command failed with following error:
    `An unexpected error has occurred during the last operation.`     Additionally, a traceback was also logged.
    With this update, the error message has been improved and failure to run no longer logs a traceback.

    This RHUI update introduces the following enhancements:

    * With this update, the client configuration RPMs in `rhui-manager` prevent subscription manager from     automatically enabling `yum` plugins. As a result, RHUI repository users will no longer see irrelevant     messages from subscription manager. (BZ#1957871)

    * With this update, you can generate machine-readable files with the status of each RHUI repository. To     use this feature, run the following command:
    `rhui-manager --non-interactive status --repo_json <output file>`      (BZ#2079391)

    * With this update, the `rhui-manager` CLI command uses a variety of unique exit codes to indicate     different types of errors. For example, if you attempt to add a Red Hat repository that has already been     added, the command will exit with a status of 245. However, if you attempt to add a Red Hat repository     that does not exist in the RHUI entitlement, the command will exit with a status of 246. For a complete     list of codes, see the `/usr/lib/python3.6/site-packages/rhui/common/rhui_exit_codes.py` file.

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.
