JSON API - Moderately critical - Multiple Vulnerabilities - SA-CONTRIB-2018-015

Wed, 21/02/2018 - 20:12
Project: JSON APIDate: 2018-February-21Security risk: Moderately critical 13∕25 AC:Complex/A:User/CI:Some/II:Some/E:Theoretical/TD:AllVulnerability: Multiple Vulnerabilities Description: 

This module provides a JSON API standards-compliant API for accessing and manipulating Drupal content and configuration entities.

  • The module doesn't sufficiently associate cacheability metadata in certain situations thereby causing an access bypass vulnerability.

    This vulnerability is mitigated by the fact that an attacker cannot trigger an exploitable situation themselves.

  • The module doesn't sufficiently check access in certain situations.

    This vulnerability is mitigated by the fact that an attacker must have permission to create entities of certain content entity types.

Update: This is fixed in 8.x-1.10 not 8.x-1.9Solution:

Custom Permissions - Moderately critical - Access bypass - SA-CONTRIB-2018-010

Wed, 14/02/2018 - 18:28
Project: Custom PermissionsVersion: 7.x-2.x-devDate: 2018-February-14Security risk: Moderately critical 14∕25 AC:None/A:User/CI:Some/II:Some/E:Theoretical/TD:UncommonVulnerability: Access bypassDescription: 

This module enables the user to set custom permissions per path.

The module doesn't perform sufficient checks on paths with dynamic arguments (like "node/1" or "user/2"), thereby allowing the site administrator to save custom permissions for paths that won't be protected. This could lead to an access bypass vulnerability if the site is relying on the Custom Permissions module to protect those paths.

This vulnerability is mitigated by the fact that it only occurs on sites which attempted to use the Custom Permissions module to protect dynamic paths.

Solution: 

Install the latest version:

After installing the latest version, visit Administration → People → Custom Permissions (admin/people/custom_permissions) and save the form. If it saves with no errors, your site is not vulnerable. However, if an error message is displayed informing you that the module is attempting to protect paths with dynamic arguments that it is unable to protect, your site requires a manual fix; you should reconfigure the site to use a different method to protect these paths (for example, use "node/*" to protect all nodes with the same permission, rather than "node/1" to try to protect only a specific node; or, alternatively, use a node access module to protect the node-related paths with fine-grained access control).

Entity Reference Tab / Accordion Formatter - Moderately critical - Cross Site Scripting - SA-CONTRIB-2018-008

Wed, 07/02/2018 - 18:45
Project: Entity Reference Tab / Accordion FormatterDate: 2018-February-07Security risk: Moderately critical 14∕25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:AllVulnerability: Cross Site ScriptingDescription: 

This module enables you to show referenced entities in tabs.

The module doesn't sufficiently sanitize the body fields of the referenced entities when it prints them to the tabs.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission create/edit content of the content type that is referenced.

Solution: 

Install the latest version:

  • If you use the Entity Reference Tab / Accordion Formatter module for Drupal 8.x, upgrade to 8.x-1.3

This module provides an expandable tree widget for the Taxonomy Term Reference field in Drupal 7.

The module doesn't sufficiently sanitize the output of its own defined field formatter.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission that allows to edit terms of a taxonomy where the module handles its output.

Solution: 

Install the latest version:

  • If you use the Taxonomy Term Reference Tree Widget module for Drupal 7.x, upgrade to its 7.x-1.11

Sagepay - Critical - Access Bypass - SA-CONTRIB-2018-005

Wed, 31/01/2018 - 17:47
Project: SagepayVersion: 7.x-1.4Date: 2018-January-31Security risk: Critical 15∕25 AC:None/A:None/CI:Some/II:None/E:Theoretical/TD:AllVulnerability: Access BypassDescription: 

This module integrates the Sagepay payment service.

Some of the URLs used while processing the payment are not sufficiently secured. This might allow attackers to resume a previously failed payment attempt or to view content that should only be shown after a succesful payment. This affects all payments in a Drupal installation with this module enabled (including payments made using other payment methods).

Solution: 

Install the latest version:

Also see the Sagepay project page.

Backup and Migrate - Critical - Arbitrary PHP code execution - SA-CONTRIB-2018-004

Wed, 24/01/2018 - 18:32
Project: Backup and MigrateDate: 2018-January-24Security risk: Critical 15∕25 AC:Basic/A:User/CI:Some/II:All/E:Theoretical/TD:DefaultVulnerability: Arbitrary PHP code executionDescription: 

This module enables you to create manual and scheduled backups of a site, and restore the site from backup.

The module doesn't sufficiently identify that its custom permissions are risky and should only be granted to highly trusted roles.

Sites using this module should review the permissions page to verify only trusted users are granted permissions defined by the module.

Bible - Critical - Multiple Vulnerabilities - SA-CONTRIB-2018-003

Wed, 17/01/2018 - 18:46
Project: BibleDate: 2018-January-17Security risk: Critical 17∕25 AC:Basic/A:User/CI:Some/II:All/E:Proof/TD:AllVulnerability: Multiple Vulnerabilities Description: 

This module enables you to display a Bible on your website. Users can associate notes with a Bible version.

This module has a vulnerability that would allow an attacker to wipe out, update or read notes from other users with a carefully crafted title.

A user must have the "Access Bible content" privilege, which is most likely the default if you have enabled this module.

The code appeared to allow other SQL injection vulnerabilities as well. Many lines of code were rewritten to make this module more secure. Therefore, even if you did not give users the "Access Bible content" privilege, there may have been other SQL vulnerabilities which could have been exploited.

Solution: 

Install the latest version:

  • If you use the Bible module for Drupal 7.x, upgrade to Bible 7.x-1.7

Node View Permissions - Moderately critical - Access Bypass - SA-CONTRIB-2018-002

Wed, 10/01/2018 - 18:02
Project: Node View PermissionsVersion: 8.x-1.x-dev7.x-1.x-devDate: 2018-January-10Security risk: Moderately critical 14∕25 AC:None/A:None/CI:Some/II:None/E:Theoretical/TD:DefaultVulnerability: Access BypassDescription: 

The Node view permissions module enables the "View own content" and "View any content" permissions for each content type on the permissions page.

This module has a vulnerability that allows users with these permissions to view unpublished content that they are not otherwise authorized to view.

This issue was fixed by the maintainer outside of the normal security team protocols. Some issues were patched in 2014 for the 7.x version of this module. The 8.x release was updated within the last 6 months. Both are now flagged as security updates.

Project: StacksDate: 2018-January-10Security risk: Critical 18∕25 AC:None/A:None/CI:Some/II:Some/E:Theoretical/TD:AllVulnerability: Arbitrary PHP code executionDescription: 

This module enables content editors to create complex pages and layouts on the fly without the help from a developer, using reusable widgets.
The module does not sufficiently filter values posted to its AJAX endpoint, which leads to the instantiation of an arbitrary PHP class.
This vulnerability is mitigated by the fact that only sites with the Stacks - Content Feed submodule enabled are affected.

Solution: 

Install the latest version:

  • If you use the Stacks module for Drupal 8.x, upgrade to Stacks 8.x-1.1
