Drupal core sanitizes filenames with dangerous extensions upon upload (reference: SA-CORE-2020-012) and strips leading and trailing dots from filenames to prevent uploading server configuration files (reference: SA-CORE-2019-010). However, the protections for these two vulnerabilities previously did not work correctly together. As a result, if the site were configured to allow the upload of files with an htaccess extension, these files' filenames would not be properly sanitized. This could allow bypassing the protections provided by Drupal core's default .htaccess files and possible remote code execution on Apache web servers. This issue is mitigated by the fact that it requires a field administrator to explicitly configure a file field to allow htaccess as an extension (a restricted permission), or a contributed module or custom code that overrides allowed file uploads.

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

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

  - Drupal core sanitizes filenames with dangerous extensions upon upload (reference: SA-CORE-2020-012) and
    strips leading and trailing dots from filenames to prevent uploading server configuration files
    (reference: SA-CORE-2019-010). However, the protections for these two vulnerabilities previously did not
    work correctly together. As a result, if the site were configured to allow the upload of files with an
    htaccess extension, these files' filenames would not be properly sanitized. This could allow bypassing the
    protections provided by Drupal core's default .htaccess files and possible remote code execution on Apache
    web servers. This issue is mitigated by the fact that it requires a field administrator to explicitly
    configure a file field to allow htaccess as an extension (a restricted permission), or a contributed
    module or custom code that overrides allowed file uploads. (CVE-2022-25277)

According to its self-reported version, the instance of Drupal running on the remote web server is 7.x prior to 7.91, 9.3.x prior to 9.3.19, or 9.4.x prior to 9.4.3. It is, therefore, affected by multiple vulnerabilities.

  - The Media oEmbed iframe route does not properly validate the iframe domain setting, which allows embeds to     be displayed in the context of the primary domain. Under certain circumstances, this could lead to cross-     site scripting, leaked cookies, or other vulnerabilities. This advisory is not covered by Drupal Steward.
    (CVE-2022-25276)

  - Updated 2022-07-20 19:45 UTC to indicate that this only affects Apache web servers. Drupal core sanitizes     filenames with dangerous extensions upon upload (reference: SA-CORE-2020-012) and strips leading and     trailing dots from filenames to prevent uploading server configuration files (reference: SA-     CORE-2019-010). However, the protections for these two vulnerabilities previously did not work correctly     together. As a result, if the site were configured to allow the upload of files with an htaccess     extension, these files' filenames would not be properly sanitized. This could allow bypassing the     protections provided by Drupal core's default .htaccess files and possible remote code execution on Apache     web servers. This issue is mitigated by the fact that it requires a field administrator to explicitly     configure a file field to allow htaccess as an extension (a restricted permission), or a contributed     module or custom code that overrides allowed file uploads. (CVE-2022-25277)

  - Under certain circumstances, the Drupal core form API evaluates form element access incorrectly. This may     lead to a user being able to alter data they should not have access to. No forms provided by Drupal core     are known to be vulnerable. However, forms added through contributed or custom modules or themes may be     affected. This advisory is not covered by Drupal Steward. (CVE-2022-25278)

  - In some situations, the Image module does not correctly check access to image files not stored in the     standard public files directory when generating derivative images using the image styles system. Access to     a non-public file is checked only if it is stored in the private file system. However, some contributed     modules provide additional file systems, or schemes, which may lead to this vulnerability. This     vulnerability is mitigated by the fact that it only applies when the site sets (Drupal 9)     $config['image.settings']['allow_insecure_derivatives'] or (Drupal 7)     $conf['image_allow_insecure_derivatives'] to TRUE. The recommended and default setting is FALSE, and     Drupal core does not provide a way to change that in the admin UI. Some sites may require configuration     changes following this security release. Review the release notes for your Drupal version if you have     issues accessing files or image styles after updating. (CVE-2022-25275)

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