Drupal

Project: Drupal coreDate: 2024-November-20Security risk: Moderately critical 14 ∕ 25 AC:Complex/A:Admin/CI:All/II:All/E:Theoretical/TD:UncommonVulnerability: Gadget chainAffected versions: >=7.0 < 7.102 || >= 8.0.0 < 10.2.11 || >= 10.3.0 < 10.3.9Description: 

Drupal core contains a potential PHP Object Injection vulnerability that (if combined with another exploit) could lead to Remote Code Execution. It is not directly exploitable.

This issue is mitigated by the fact that in order for it to be exploitable, a separate vulnerability must be present to allow an attacker to pass unsafe input to unserialize(). There are no such known exploits in Drupal core.

To help protect against this potential vulnerability, some additional checks have been added to Drupal core's database code. If you use a third-party database driver, check the release notes for additional configuration steps that may be required in certain cases.

Solution: 

Install the latest version:

• If you are using Drupal 7, update to Drupal 7.102.
• If you are using Drupal 10.2, update to Drupal 10.2.11.
• If you are using Drupal 10.3, update to Drupal 10.3.9.

All versions of Drupal 10 prior to 10.2 are end-of-life and do not receive security coverage. (Drupal 8 and Drupal 9 have both reached end-of-life.)

This issue is mitigated by the fact that in order for it to be exploitable, a separate vulnerability must be present to allow an attacker to pass unsafe input to unserialize(). There are no such known exploits in Drupal core.

To help protect against this potential vulnerability, types have been added to properties in some of Drupal core's classes. If an application extends those classes, the same types may need to be specified on the subclass to avoid a TypeError.

Solution: 

Install the latest version:

• If you are using Drupal 10.2, update to Drupal 10.2.11.
• If you are using Drupal 10.3, update to Drupal 10.3.9.

Project: Drupal coreDate: 2024-November-20Security risk: Critical 17 ∕ 25 AC:None/A:None/CI:Some/II:Some/E:Theoretical/TD:DefaultVulnerability: Cross Site ScriptingAffected versions: >=7.0 <7.102Description: 

Drupal 7 core's Overlay module doesn't safely handle user input, leading to reflected cross-site scripting under certain circumstances.

Only sites with the Overlay module enabled are affected by this vulnerability.

Solution: 

Install the latest version:

• If you are using Drupal 7, update to Drupal 7.102
• Sites may also disable the Overlay module to avoid the issue.

Drupal 10 and Drupal 11 are not affected, as the Overlay module was removed from Drupal core in Drupal 8.

Drupal's uniqueness checking for certain user fields is inconsistent depending on the database engine and its collation.

As a result, a user may be able to register with the same email address as another user.

This may lead to data integrity issues.

Solution: 

Install the latest version:

• If you are using Drupal 10.2, update to Drupal 10.2.11.
• If you are using Drupal 10.3, update to Drupal 10.3.9.
• If you are using Drupal 11.0, update to Drupal 11.0.8.

Updating Drupal will not solve potential issues with existing accounts affected by this bug. See Fixing emails that vary only by case for additional guidance.

Project: Drupal coreDate: 2024-October-16Security risk: Moderately critical 13 ∕ 25 AC:Basic/A:None/CI:None/II:All/E:Theoretical/TD:UncommonVulnerability: Improper error handlingAffected versions: >=10.0 < 10.2.10Description: 

Under certain uncommon site configurations, a bug in the CKEditor 5 module can cause some image uploads to move the entire webroot to a different location on the file system. This could be exploited by a malicious user to take down a site.

The issue is mitigated by the fact that several non-default site configurations must exist simultaneously for this to occur.

Solution: 

Install the latest version:

• If you are using Drupal 10.2, update to Drupal 10.2.10.
• Drupal 10.3 and above are not affected, nor is Drupal 7.

All versions of Drupal 10 prior to 10.2 are end-of-life and do not receive security coverage. (Drupal 8 and Drupal 9 have both reached end-of-life.)
