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

Biztonsági figyelmeztetések (core) - 2020. november 26. 00.57
Project: Drupal coreDate: 2020-November-25Security risk: Critical 18∕25 AC:Complex/A:User/CI:All/II:All/E:Exploit/TD:UncommonVulnerability: Arbitrary PHP code executionCVE IDs: CVE-2020-28949CVE-2020-28948Description: 

The Drupal project uses the PEAR Archive_Tar library. The PEAR Archive_Tar library has released a security update that impacts Drupal. For more information please see:

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, similar configuration changes may mitigate the problem until you are able to patch.

Solution: 

Install the latest version:

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, 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.

Drupal core - Critical - Remote code execution - SA-CORE-2020-012

Biztonsági figyelmeztetések (core) - 2020. november 18. 18.18
Project: Drupal coreDate: 2020-November-18Security risk: Critical 17∕25 AC:Basic/A:User/CI:All/II:All/E:Theoretical/TD:DefaultVulnerability: Remote code executionCVE IDs: CVE-2020-13671Description: 

Update November 18: Documented longer list of dangerous file extensions

Drupal core does not properly sanitize certain filenames on uploaded files, which can lead to files being interpreted as the incorrect extension and served as the wrong MIME type or executed as PHP for certain hosting configurations.

Solution: 

Install the latest version:

Versions of Drupal 8 prior to 8.8.x are end-of-life and do not receive security coverage.

Additionally, it's recommended that you audit all previously uploaded files to check for malicious extensions. Look specifically for files that include more than one extension, like filename.php.txt or filename.html.gif, without an underscore (_) in the extension. Pay specific attention to the following file extensions, which should be considered dangerous even when followed by one or more additional extensions:

  • phar
  • php
  • pl
  • py
  • cgi
  • asp
  • js
  • html
  • htm
  • phtml

This list is not exhaustive, so evaluate security concerns for other unmunged extensions on a case-by-case basis.

Therefore, File Example so is being removed from Examples until a version demonstrating file security best practices can added back in the future.

Solution: 

Any sites that have File Example submodule installed should uninstall it immediately

Then, install the latest version of Examples:
