Drupal core - Moderately critical - Third-party libraries - SA-CORE-2019-007

2019. május 8. 18.56
Project: Drupal coreDate: 2019-May-08Security risk: Moderately critical 14∕25 AC:Complex/A:Admin/CI:All/II:All/E:Theoretical/TD:UncommonVulnerability: Third-party librariesDescription: 

This security release fixes third-party dependencies included in or required by Drupal core. As described in TYPO3-PSA-2019-007: By-passing protection of Phar Stream Wrapper Interceptor:

In order to intercept file invocations like file_exists or stat on compromised Phar archives the base name has to be determined and checked before allowing to be handled by PHP Phar stream handling. [...]

The current implementation is vulnerable to path traversal leading to scenarios where the Phar archive to be assessed is not the actual (compromised) file.

Solution: 

Install the latest version:

Versions of Drupal 8 prior to 8.6.x are end-of-life and do not receive security coverage.

Drupal core - Moderately critical - Cross Site Scripting - SA-CORE-2019-006

2019. április 17. 22.30
Project: Drupal coreDate: 2019-April-17Security risk: Moderately critical 10∕25 AC:Complex/A:Admin/CI:Some/II:Some/E:Theoretical/TD:UncommonVulnerability: Cross Site ScriptingDescription: 

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.

Solution: 

Install the latest version:

Versions of Drupal 8 prior to 8.5.x are end-of-life and do not receive security coverage.

Drupal core - Moderately critical - Multiple Vulnerabilities - SA-CORE-2019-005

2019. április 17. 22.29
Project: Drupal coreDate: 2019-April-17Security risk: Moderately critical 14∕25 AC:Basic/A:User/CI:Some/II:Some/E:Proof/TD:DefaultVulnerability: Multiple Vulnerabilities Description: 

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).

Solution: 

Install the latest version:

Versions of Drupal 8 prior to 8.5.x are end-of-life and do not receive security coverage.

Drupal core - Moderately critical - Cross Site Scripting - SA-CORE-2019-004

2019. március 20. 17.08
Project: Drupal coreDate: 2019-March-20Security risk: Moderately critical 13∕25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:DefaultVulnerability: Cross Site ScriptingDescription: 

Under certain circumstances the File module/subsystem allows a malicious user to upload a file that can trigger a cross-site scripting (XSS) vulnerability.

Solution: 

Versions of Drupal 8 prior to 8.5.x are end-of-life and do not receive security coverage.

Drupal core - Highly critical - Remote Code Execution - SA-CORE-2019-003

2019. február 20. 20.18
Project: Drupal coreDate: 2019-February-20Security risk: Highly critical 20∕25 AC:None/A:None/CI:All/II:All/E:Theoretical/TD:UncommonVulnerability: Remote Code ExecutionCVE IDs: CVE-2019-6340Description: 

Some field types do not properly sanitize data from non-form sources. This can lead to arbitrary PHP code execution in some cases.

A site is only affected by this if one of the following conditions is met:

  • The site has the Drupal 8 core RESTful Web Services (rest) module enabled and allows PATCH or POST requests, or
  • the site has another web services module enabled (like JSON:API in Drupal 8, or Services or RESTful Web Services in Drupal 7).
Solution: 

Versions of Drupal 8 prior to 8.5.x are end-of-life and do not receive security coverage.

To immediately mitigate the vulnerability, you can disable all web services modules, or configure your web server(s) to not allow PUT/PATCH/POST requests to web services resources. Note that web services resources may be available on multiple paths depending on the configuration of your server(s). For Drupal 7, resources are for example typically available via paths (clean URLs) and via arguments to the "q" query argument. For Drupal 8, paths may still function when prefixed with index.php/.
