View online: https://www.drupal.org/sa-contrib-2018-15 Project: JSON API [1] Date: 2018-February-21 Security risk: *Moderately critical* 13∕25 AC:Complex/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2] Vulnerability: 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. Solution: Install the latest version: * If you use the JSON API module for Drupal 8.x, upgrade to JSON API 8.x-1.9 [3] Reported By: * Wim Leers [4] * Gabe Sullice [5] * Aaron Clemmer [6] Fixed By: * Wim Leers [7] * Mateu Aguiló Bosch [8] * Gabe Sullice [9] Coordinated By: * Michael Hess [10] of the Drupal Security Team [1] https://www.drupal.org/project/jsonapi [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/jsonapi/releases/8.x-1.9 [4] https://www.drupal.org/user/99777 [5] https://www.drupal.org/user/2287430 [6] https://www.drupal.org/u/acamer32 [7] https://www.drupal.org/user/99777 [8] https://www.drupal.org/user/550110 [9] https://www.drupal.org/user/2287430 [10] https://www.drupal.org/u/mlhess

Drupal core - Critical - Multiple Vulnerabilities - SA-CORE-2018-001
by security-news＠drupal.org 21 Feb '18

21 Feb '18

View online: https://www.drupal.org/sa-core-2018-001 Project: Drupal core [1] Version: 8.4.x-dev7.x-dev Date: 2018-February-21 Security risk: *Critical* 16∕25 AC:Basic/A:User/CI:Some/II:Some/E:Exploit/TD:Default [2] Vulnerability: Multiple Vulnerabilities Description: .. Comment reply form allows access to restricted content - Critical - Drupal 8 Users with permission to post comments are able to view content and comments they do not have access to, and are also able to add comments to this content. This vulnerability is mitigated by the fact that the comment system must be enabled and the attacker must have permission to post comments. .. JavaScript cross-site scripting prevention is incomplete - Critical - Drupal 7 and Drupal 8 Drupal has a Drupal.checkPlain() JavaScript function which is used to escape potentially dangerous text before outputting it to HTML. This function does not correctly handle all methods of injecting malicious HTML, leading to a cross-site scripting vulnerability under certain circumstances. The PHP functions which Drupal provides for HTML escaping are not affected. .. Private file access bypass - Moderately Critical - Drupal 7 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. .. jQuery vulnerability with untrusted domains - Moderately Critical - Drupal A jQuery cross site scripting vulnerability is present when making Ajax requests to untrusted domains. This vulnerability is mitigated by the fact that it requires contributed or custom modules in order to exploit. For Drupal 8, this vulnerability was already fixed in Drupal 8.4.0 as a side effect of upgrading Drupal core to use a newer version of jQuery. For Drupal 7, it is fixed in the current release (Drupal 7.57) for jQuery 1.4.4 (the version that ships with Drupal 7 core) as well as for other newer versions of jQuery that might be used on the site, for example using the jQuery Update module [3]. .. Language fallback can be incorrect on multilingual sites with node access restrictions - Moderately Critical - Drupal 8 When using node access controls with a multilingual site, Drupal marks the untranslated version of a node as the default fallback for access queries. This fallback is used for languages that do not yet have a translated version of the created node. This can result in an access bypass vulnerability. This issue is mitigated by the fact that it only applies to sites that a) use the Content Translation module; and b) use a node access module such as Domain Access which implement hook_node_records(). /Note that the update will mark the node access tables as needing a rebuild, which will take a long time on sites with a large number of nodes./ .. Settings Tray access bypass - Moderately Critical - Drupal 8 The Settings Tray module has a vulnerability that allows users to update certain data that they do not have the permissions for. If you have implemented a Settings Tray form in contrib or a custom module, the correct access checks should be added. This release fixes the only two implementations in core, but does not harden against other such bypasses. This vulnerability can be mitigated by disabling the Settings Tray module. .. External link injection on 404 pages when linking to the current page - Less Critical - Drupal 7 Drupal core has an external link injection vulnerability when the language switcher block is used. A similar vulnerability exists in various custom and contributed modules. This vulnerability could allow an attacker to trick users into unwillingly navigating to an external site. Solution: Install the latest version: * If you are using Drupal 8 , upgrade to Drupal 8.4.5 [4] * If you are using Drupal 7 , upgrade to Drupal 7.57 [5] Reported By: * ..

Entity API - Moderately critical - Information Disclosure - SA-CONTRIB-2018-013

The module prints debugging information to the HTML output in certain error conditions thereby causing an information disclosure vulnerability. This vulnerability is mitigated by the fact that an attacker needs to be able to trigger the error condition in a way that protected data is exposed.

Custom Permissions - Moderately critical - Access bypass - SA-CONTRIB-2018-010
by security-news＠drupal.org 14 Feb '18

View online: https://www.drupal.org/sa-contrib-2018-010 Project: Custom Permissions [1] Version: 7.x-2.x-dev Date: 2018-February-14 Security risk: *Moderately critical* 14∕25 AC:None/A:User/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2] Vulnerability: Access bypass Description: 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: * If you use the Custom Permissions module for Drupal 7.x, upgrade to Custom Permissions 7.x-2.2 [3] 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).
