Under some circumstances, the Drupal core JSON:API module does not properly restrict access to certain content, which may result in unintended access bypass. Sites that do not have the JSON:API module enabled are not affected.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Under some circumstances, the Drupal core JSON:API module does not properly restrict access to certain     content, which may result in unintended access bypass. Sites that do not have the JSON:API module enabled     are not affected. (CVE-2020-13677)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Under some circumstances, the Drupal core JSON:API module does not properly restrict access to certain
    content, which may result in unintended access bypass. Sites that do not have the JSON:API module enabled
    are not affected. (CVE-2020-13677)

According to its self-reported version, the instance of Drupal running on the remote web server is 8.9.x prior to 8.9.19, 9.1.x prior to 9.1.13, or 9.2.x prior to 9.2.6. It is, therefore, affected by multiple vulnerabilities.

 - Under some circumstances, the Drupal core JSON:API module does not properly restrict access to certain content, which may result in unintended access bypass. Sites that do not have the JSON:API module enabled are not affected. (CVE-2020-13677)

 - The QuickEdit module does not properly check access to fields in some circumstances, which can lead to unintended disclosure of field data. Sites are only affected if the QuickEdit module (which comes with the Standard profile) is installed. (CVE-2020-13676)

 - Drupal's JSON:API and REST/File modules allow file uploads through their HTTP APIs. The modules do not correctly run all file validation, which causes an access bypass vulnerability. An attacker might be able to upload files that bypass the file validation process implemented by modules on the site. This vulnerability is mitigated by three factors: The JSON:API or REST File upload modules must be enabled on the site. An attacker must have access to a file upload via JSON:API or REST. The site must employ a file validation module. (CVE-2020-13675)

 - The QuickEdit module does not properly validate access to routes, which could allow cross-site request forgery under some circumstances and lead to possible data integrity issues. Sites are only affected if the QuickEdit module (which comes with the Standard profile) is installed. Removing the access in-place editing permission from untrusted users will not fully mitigate the vulnerability. (CVE-2020-13674)

 - The Drupal core Media module provides a filter to allow embedding internal and external media in content fields. In certain circumstances, the filter could allow an unprivileged user to inject HTML into a page when it is accessed by a trusted user with permission to embed media. In some cases, this could lead to cross-site scripting. (CVE-2020-13673)

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