Drupal core 7.x versions before 7.57 when using Drupal's private file system, Drupal will check to make sure a user has access to a file before allowing the user to view or download it. This check fails under certain conditions in which one module is trying to grant access to the file and another is trying to deny it, leading to an access bypass vulnerability. This vulnerability is mitigated by the fact that it only occurs for unusual site configurations.

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

  - Drupal core 7.x versions before 7.57 when using Drupal's private file system, Drupal will check to make
    sure a user has access to a file before allowing the user to view or download it. This check fails under
    certain conditions in which one module is trying to grant access to the file and another is trying to deny
    it, leading to an access bypass vulnerability. This vulnerability is mitigated by the fact that it only
    occurs for unusual site configurations. (CVE-2017-6928)

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

  - Drupal core 7.x versions before 7.57 when using Drupal's private file system, Drupal will check to make     sure a user has access to a file before allowing the user to view or download it. This check fails under     certain conditions in which one module is trying to grant access to the file and another is trying to deny     it, leading to an access bypass vulnerability. This vulnerability is mitigated by the fact that it only     occurs for unusual site configurations. (CVE-2017-6928)

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

According to its self-reported version, the instance of Drupal running on the remote web server is 7.x prior to 7.57. It is, therefore, affected by multiple vulnerabilities :

  - A flaw exists with the Drupal.checkPlain() function due to     improper handling of HTML injection. A remote attacker, with a     specially crafted request, could potentially execute arbitrary     script code within the trust relationship between the browser and     server. (CVE-2017-6927)

  - A flaw exists with the private file system due to improper checking     of permissions when modules provided conflicting access. A remote     attacker could potentially access sensitive files. (CVE-2017-6928)

  - A flaw exists with the bundled jQuery due to improper handling of     Ajax requests. A remote attacker, with a specially crafted request,     could potentially execute arbitrary script code within the trust     relationship between the browser and server. (CVE-2017-6929)

  - A flaw exists with the language switcher block due to improper     validation of user input. A context-dependent attacker, with a     specially crafted link, could redirect a user to a malicious site.
    (CVE-2017-6932)

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

Multiple vulnerabilities have been found in the Drupal content management framework. For additional information, please refer to the upstream advisory at https://www.drupal.org/sa-core-2018-001.

For Debian 7 'Wheezy', these problems have been fixed in version 7.14-2+deb7u17.
