The version of Wordpress Core installed on the remote host are affected by multiple vulnerabilities.

  - The Popup Builder WordPress plugin through 4.1.15 does not sanitise and escape some of its settings,     which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks     even when the unfiltered_html capability is disallowed (for example in multisite setup). (CVE-2023-5561)

  - Auth. Stored (contributor+) Cross-Site Scripting (XSS). (CVE-2023-38000)

  - Exposure of Sensitive Information to an Unauthorized Actor. (CVE-2023-39999)

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

The remote Fedora 38 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-c42a4b2eab advisory.

    Several security vulnerabilities have been discovered in Wordpress, a     popular content management framework, which may lead to exposure of sensitive     information to an unauthorized actor in WordPress or allowing unauthenticated     attackers to discern the email addresses of users who have published public     posts on an affected website via an Oracle style attack.

    For Debian 10 buster, these problems have been fixed in version     5.0.20+dfsg1-0+deb10u1.

    We recommend that you upgrade your wordpress packages.

The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5685 advisory.

  - WordPress Core is vulnerable to Directory Traversal in versions up to, and including, 6.2, via the     wp_lang' parameter. This allows unauthenticated attackers to access and load arbitrary translation files.
    In cases where an attacker is able to upload a crafted translation file onto the site, such as via an     upload form, this could be also used to perform a Cross-Site Scripting attack. (CVE-2023-2745)

  - Auth. Stored (contributor+) Cross-Site Scripting (XSS) vulnerability in WordPress core 6.3 through 6.3.1,     from 6.2 through 6.2.2, from 6.1 through 6.1.3, from 6.0 through 6.0.5, from 5.9 through 5.9.7 and     Gutenberg plugin <= 16.8.0 versions. (CVE-2023-38000)

  - Exposure of Sensitive Information to an Unauthorized Actor in WordPress from 6.3 through 6.3.1, from 6.2     through 6.2.2, from 6.1 through 6.13, from 6.0 through 6.0.5, from 5.9 through 5.9.7, from 5.8 through     5.8.7, from 5.7 through 5.7.9, from 5.6 through 5.6.11, from 5.5 through 5.5.12, from 5.4 through 5.4.13,     from 5.3 through 5.3.15, from 5.2 through 5.2.18, from 5.1 through 5.1.16, from 5.0 through 5.0.19, from     4.9 through 4.9.23, from 4.8 through 4.8.22, from 4.7 through 4.7.26, from 4.6 through 4.6.26, from 4.5     through 4.5.29, from 4.4 through 4.4.30, from 4.3 through 4.3.31, from 4.2 through 4.2.35, from 4.1     through 4.1.38. (CVE-2023-39999)

  - WordPress does not properly restrict which user fields are searchable via the REST API, allowing     unauthenticated attackers to discern the email addresses of users who have published public posts on an     affected website via an Oracle style attack (CVE-2023-5561)

  - WordPress is an open publishing platform for the Web. It's possible for a file of a type other than a zip     file to be submitted as a new plugin by an administrative user on the Plugins -> Add New -> Upload Plugin     screen in WordPress. If FTP credentials are requested for installation (in order to move the file into     place outside of the `uploads` directory) then the uploaded file remains temporary available in the Media     Library despite it not being allowed. If the `DISALLOW_FILE_EDIT` constant is set to `true` on the site
    _and_ FTP credentials are required when uploading a new theme or plugin, then this technically allows an     RCE when the user would otherwise have no means of executing arbitrary PHP code. This issue _only_ affects     Administrator level users on single site installations, and Super Admin level users on Multisite     installations where it's otherwise expected that the user does not have permission to upload or execute     arbitrary PHP code. Lower level users are not affected. Sites where the `DISALLOW_FILE_MODS` constant is     set to `true` are not affected. Sites where an administrative user either does not need to enter FTP     credentials or they have access to the valid FTP credentials, are not affected. The issue was fixed in     WordPress 6.4.3 on January 30, 2024 and backported to versions 6.3.3, 6.2.4, 6.1.5, 6.0.7, 5.9.9, 5.8.9,     5.7.11, 5.6.13, 5.5.14, 5.4.15, 5.3.17, 5.2.20, 5.1.18, 5.0.21, 4.9.25, 2.8.24, 4.7.28, 4.6.28, 4.5.31,     4.4.32, 4.3.33, 4.2.37, and 4.1.40. A workaround is available. If the `DISALLOW_FILE_MODS` constant is     defined as `true` then it will not be possible for any user to upload a plugin and therefore this issue     will not be exploitable. (CVE-2024-31210)

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

The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-c1535224de advisory.
