According to its self-reported version number, the detected Drupal application is affected by multiple vulnerabilities :

 - Several flaws exist in third-party Symfony PHP framework.

 - A flaw exists in third-party jQuery JavaScript library.

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

Multiple vulnerabilities were discovered in the Symfony PHP framework which could lead to cache bypass, authentication bypass, information disclosure, open redirect, cross-site request forgery, deletion of arbitrary files, or arbitrary code execution.

According to its self-reported version, the instance of Drupal running on the remote web server is 7.x prior to 7.66, 8.5.x prior to 8.5.15, or 8.6.x prior to 8.6.15. It is, therefore, affected by multiple vulnerabilities.

  - The jQuery project released version 3.4.0, and as part     of that, disclosed a security vulnerability that affects     all prior versions. As described in their release notes:
    jQuery 3.4.0 includes a fix for some unintended behavior     when using jQuery.extend(true, {}, ...). If an     unsanitized source object contained an enumerable
    __proto__ property, it could extend the native     Object.prototype. This fix is included in jQuery 3.4.0,     but patch diffs exist to patch previous jQuery versions.
    It's possible that this vulnerability is exploitable     with some Drupal modules. As a precaution, this Drupal     security release backports the fix to jQuery.extend(),     without making any other changes to the jQuery version     that is included in Drupal core (3.2.1 for Drupal 8 and     1.4.4 for Drupal 7) or running on the site via some     other module such as jQuery Update. (SA-CORE-2019-006)

  - This security release fixes third-party dependencies     included in or required by Drupal core. CVE-2019-10909:
    Escape validation messages in the PHP templating engine.
    From that advisory:Validation messages were not escaped     when using the form theme of the PHP templating engine     which, when validation messages may contain user input,     could result in an XSS. CVE-2019-10910: Check service     IDs are valid. From that advisory: Service IDs derived     from unfiltered user input could result in the execution     of any arbitrary code, resulting in possible remote code     execution. CVE-2019-10911: Add a separator in the     remember me cookie hash. From that advisory: This fixes     situations where part of an expiry time in a cookie     could be considered part of the username, or part of the     username could be considered part of the expiry time. An     attacker could modify the remember me cookie and     authenticate as a different user. This attack is only     possible if remember me functionality is enabled and the     two users share a password hash or the password hashes     (e.g. UserInterface::getPassword()) are null for all     users (which is valid if passwords are checked by an     external system, e.g. an SSO). (CVE-2019-10909,     CVE-2019-10910, CVE-2019-10911)

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

Drupal Security Team reports :

CVE-2019-10909: Escape validation messages in the PHP templating engine.

jQuery 3.4.0 includes a fix for some unintended behavior when using jQuery.extend(true, {}, ...). If an unsanitized source object contained an enumerable __proto__ property, it could extend the native Object.prototype. This fix is included in jQuery 3.4.0, but patch diffs exist to patch previous jQuery versions.

It's possible that this vulnerability is exploitable with some Drupal modules. As a precaution, this Drupal security release backports the fix to jQuery.extend(), without making any other changes to the jQuery version that is included in Drupal core (3.2.1 for Drupal 8 and 1.4.4 for Drupal 7) or running on the site via some other module such as jQuery Update.

Several security vulnerabilities have been discovered in symfony, a PHP web application framework. Numerous symfony components are affected: Framework Bundle, Dependency Injection, Security, HttpFoundation

CVE-2019-10909

Validation messages were not escaped when using the form theme of the PHP templating engine which, when validation messages may contain user input, could result in an XSS.

For further information, see the upstream advisory at

https://symfony.com/blog/cve-2019-10909-escape-validation-messages-in- the-php-templating-engine

CVE-2019-10910

Service IDs derived from unfiltered user input could result in the execution of any arbitrary code, resulting in possible remote code execution.

For further information, see the upstream advisory at https://symfony.com/blog/cve-2019-10910-check-service-ids-ar e-valid

CVE-2019-10911

This fixes situations where part of an expiry time in a cookie could be considered part of the username, or part of the username could be considered part of the expiry time. An attacker could modify the remember me cookie and authenticate as a different user. This attack is only possible if remember me functionality is enabled and the two users share a password hash or the password hashes (e.g.
UserInterface::getPassword()) are null for all users (which is valid if passwords are checked by an external system, e.g. an SSO).

For further information, see the upstream advisory at

https://symfony.com/blog/cve-2019-10911-add-a-separator-in-the-remembe r-me-cookie-hash

CVE-2019-10913

HTTP methods, from either the HTTP method itself or using the X-Http-Method-Override header were previously returned as the method in question without validation being done on the string, meaning that they could be used in dangerous contexts when left unescaped.

For further information, see the upstream advisory at

https://symfony.com/blog/cve-2019-10913-reject-invalid-http-method-ove rrides

For Debian 8 'Jessie', these problems have been fixed in version 2.3.21+dfsg-4+deb8u5.

We recommend that you upgrade your symfony packages.
