Drupal core - Moderately critical - Access bypass - SA-CORE-2023-005

2023. április 19. 19.06
Project: Drupal coreDate: 2023-April-19Security risk: Moderately critical 13∕25 AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:AllVulnerability: Access bypassDescription: 

The file download facility doesn't sufficiently sanitize file paths in certain situations. This may result in users gaining access to private files that they should not have access to.

Some sites may require configuration changes following this security release. Review the release notes for your Drupal version if you have issues accessing private files after updating.

This advisory is covered by Drupal Steward.

We would normally not apply for a release of this severity. However, in this case we have chosen to apply Drupal Steward security coverage to test our processes.

Drupal 7
  • All Drupal 7 sites on Windows web servers are vulnerable.
  • Drupal 7 sites on Linux web servers are vulnerable with certain file directory structures, or if a vulnerable contributed or custom file access module is installed.
Drupal 9 and 10

Drupal 9 and 10 sites are only vulnerable if certain contributed or custom file access modules are installed.

Solution: 

Install the latest version:

All versions of Drupal 9 prior to 9.4.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Project: Drupal coreDate: 2023-March-15Security risk: Moderately critical 14∕25 AC:Complex/A:Admin/CI:All/II:All/E:Theoretical/TD:UncommonVulnerability: Access bypassAffected versions: <7.95 || >=8.0.0 <9.4.12 || >=9.5.0 <9.5.5 || >=10.0.0 <10.0.5Description: 

Drupal core provides a page that outputs the markup from phpinfo() to assist with diagnosing PHP configuration.

If an attacker was able to achieve an XSS exploit against a privileged user, they may be able to use the phpinfo page to access sensitive information that could be used to escalate the attack.

This vulnerability is mitigated by the fact that a successful XSS exploit is required in order to exploit it.

Solution: 

Install the latest version:

All versions of Drupal 9 prior to 9.4.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Drupal core - Moderately critical - Information Disclosure - SA-CORE-2023-003

2023. március 15. 17.24
Project: Drupal coreDate: 2023-March-15Security risk: Moderately critical 13∕25 AC:None/A:None/CI:Some/II:None/E:Theoretical/TD:UncommonVulnerability: Information DisclosureAffected versions: >=8.0.0 <9.4.12 || >=9.5.0 <9.5.5 || >=10.0.0 <10.0.5Description: 

The language module provides a Language switcher block which can be placed to provide links to quickly switch between different languages.

The URL of unpublished translations may be disclosed. When used in conjunction with a module like Pathauto, this may reveal the title of unpublished content.

This advisory is not covered by Drupal Steward.

Solution: 

Install the latest version:

All versions of Drupal 9 prior to 9.4.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Drupal 7 core does not include the Language module and therefore is not affected. The contributed modules for translation do not have the same code for language-switching links, so they are not affected, either.
