In Symfony before 2.7.51, 2.8.x before 2.8.50, 3.x before 3.4.26, 4.x before 4.1.12, and 4.2.x before 4.2.7, a vulnerability would allow an attacker to authenticate as a privileged user on sites with user registration and remember me login functionality enabled. This is related to symfony/security.

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.

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.

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.

Drupal Security Team reports :

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

CVE-2019-10910: Check service IDs are valid.

CVE-2019-10911: Add a separator in the remember me cookie hash.

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.

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.

  - 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.
