Webform - Moderately critical - Access bypass - SA-CONTRIB-2021-004

View online: https://www.drupal.org/sa-contrib-2021-004 Project: Webform [1] Date: 2021-March-03 Security risk: *Moderately critical* 12∕25 AC:Basic/A:None/CI:None/II:None/E:Exploit/TD:Default [2] Vulnerability: Access bypass Description: The Webform module for Drupal 8/9 [3] includes a default Contact webform, which sends a notification email to the site owner and a confirmation email to the email address supplied via the form. The confirmation email can be used as an open mail relay to send an email to any email address. This vulnerability is mitigated by the fact that the site owner's email address is also receiving a notification email, which should alert the site owner to the exploitation. If the site owner's mailbox is not monitored, the open mail relay can be more easily exploited. With the Webform module's latest release, the default Contact's confirmation email will only be sent to an authenticated user's email address. Anonymous users will no longer receive a confirmation email. If anonymous users need to receive a confirmation email, we recommend you add SPAM protection to the form and update the email handler. Solution: Install the latest version: * If you use the Webform module module for Drupal 8/9 upgrade to Webform 8.x-5.25 [4] or Webform 6.0.2 [5] If you are using a previous release of the Webform module you can immediately do one of several options. 1) Delete the default Contact form. (/form/contact) 2) Delete the default Contact form's confirmation email handler.(/admin/structure/webform/manage/contact/handlers) 3) Update the default Contact form's confirmation email to only email the current user's email address using the [current-user:mail] token. (/admin/structure/webform/manage/contact/handlers/email_confirmation/edit) 4) Add SPAM protection [6] to the default Contact form.

Subgroup - Less critical - Access bypass - SA-CONTRIB-2021-003

View online: https://www.drupal.org/sa-contrib-2021-003 Project: Subgroup [1] Version: 1.0.x-dev Date: 2021-January-27 Security risk: *Less critical* 9∕25 AC:Basic/A:User/CI:Some/II:None/E:Theoretical/TD:Uncommon [2] Vulnerability: Access bypass Description: This module enables you to add groups to other groups in a tree structure where access can be inherited up or down the tree. When you configure Subgroup to have a tree with at least three levels, users may inadvertently get permissions in a group that is an uncle or cousin of the source group, rather than a direct ancestor or descendant. Trees with only multiple nodes at the lowest tier (or nowhere) are unaffected. Solution: Install the latest version, Subgroup 1.0.1 [3], and clear your caches.

The module doesn't sufficiently check access when building the CSV file, allowing logged-in users without the manage members permission to be able to export all data from a selected user in certain scenarios. This vulnerability is mitigated by the fact that an attacker must have the authenticated user role and the site must have the configuration set in such a way a logged in user is able to export users. Solution: Install the latest version: * If you use Open Social major version 8, upgrade to 8.x-8.10 [3] * If you use Open Social major version 9, upgrade to 8.x-9.8 [4] Reported By: * Robert Ragas [5] Fixed By: * Ronald te Brake [6] * Alexander Varwijk [7] * Bram ten Hove [8] Coordinated By: * Greg Knaddison [9] of the Drupal Security Team [1] https://www.drupal.org/project/social [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/social/releases/8.x-8.10 [4] https://www.drupal.org/project/social/releases/8.x-9.8 [5] https://www.drupal.org/user/2723261 [6] https://www.drupal.org/user/2314038 [7] https://www.drupal.org/user/1868952 [8] https://www.drupal.org/user/1549848 [9] https://www.drupal.org/user/36762

The module doesn't implement a proper cache strategy for anonymous users allowing the registration form to be cached with disclosed information in certain scenarios. The information is usually only available for logged-in users of the community. This vulnerability is mitigated by the fact that social_auth_extra needs to be enabled, one of the single sign-on methods needs to be configured. There is no impact for regular registration without single sign-on. Removing the single sign-on providers from configuration will allow this vulnerability to be blocked. Solution: Install the latest version: * If you use Open Social major version 8, upgrade to 8.x-8.10 [3] * If you use Open Social major version 9, upgrade to 8.x-9.8 [4] Reported By: * Alexander Varwijk [5] Fixed By: * Alexander Varwijk [6] * Ronald te Brake [7] Coordinated By: * Greg Knaddison [8] of the Drupal Security Team [1] https://www.drupal.org/project/social [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/social/releases/8.x-8.10 [4] https://www.drupal.org/project/social/releases/8.x-9.8 [5] https://www.drupal.org/user/1868952 [6] https://www.drupal.org/user/1868952 [7] https://www.drupal.org/user/2314038 [8] https://www.drupal.org/user/36762

Drupal core - Critical - Arbitrary PHP code execution - SA-CORE-2020-013

The PEAR Archive_Tar library has released a security update that impacts Drupal. For more information please see: * CVE-2020-28948 [3] * CVE-2020-28949 [4] Multiple vulnerabilities are possible if Drupal is configured to allow .tar, .tar.gz, .bz2 or .tlz file uploads and processes them. *To mitigate this issue, prevent untrusted users from uploading .tar, .tar.gz, .bz2 or .tlz files.* This is a different issue than SA-CORE-2019-12 [5], similar configuration changes may mitigate the problem until you are able to patch. Solution: Install the latest version: * If you are using Drupal 9.0, update to Drupal 9.0.9 [6] * If you are using Drupal 8.9, update to Drupal 8.9.10 [7] * If you are using Drupal 8.8 or earlier, update to Drupal 8.8.12 [8] * If you are using Drupal 7, update to Drupal 7.75 [9] Versions of Drupal 8 prior to 8.8.x are end-of-life and do not receive security coverage. According to the regular security release window schedule [10], November 25th would not typically be a core security window. However, this release is necessary because there are known exploits for one of core's dependencies and some configurations of Drupal are vulnerable.
