Drupal core - Critical - Arbitrary PHP code execution - SA-CORE-2020-013
by security-news＠drupal.org 26 Nov '20

View online: https://www.drupal.org/sa-core-2020-013 Project: Drupal core [1] Date: 2020-November-25 Security risk: *Critical* 18∕25 AC:Complex/A:User/CI:All/II:All/E:Exploit/TD:Uncommon [2] Vulnerability: Arbitrary PHP code execution CVE IDs: CVE-2020-28949CVE-2020-28948 Description: 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: * 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.

Solution: Install the latest version: * If you are using Drupal 9.0, update to Drupal 9.0.8 [3] * If you are using Drupal 8.9, update to Drupal 8.9.9 [4] * If you are using Drupal 8.8 or earlier, update to Drupal 8.8.11 [5] * If you are using Drupal 7, update to Drupal 7.74 [6] 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 .php.txt or .html.gif. Reported By: * ufku [7] * Mark Ferree [8] * Frédéric G.
