Drupal releases fix for critical vulnerability with known exploits
2021-01-22 14:07

Drupal has released a security update to address a critical vulnerability in a third-party library with documented or deployed exploits available in the wild.

"The Drupal project uses the pear Archive Tar library, which has released a security update that impacts Drupal," the Drupal security team said.

Exploiting the Drupal vulnerability is only possible if the CMS is configured to allow and process.

This vulnerability is related to another critical security flaw with known exploits caused by the CVE-2020-28948 bug in the PEAR Archive Tar library that could allow for arbitrary PHP code execution on some CMS versions.

Drupal issued an out-of-band emergency security update to fix it in November allowing admins to quickly patch their servers to defend them against potential attacks.

Drupal patched another critical remote code execution vulnerability tracked as CVE-2020-13671 and allowing attackers to execute malicious code on vulnerable servers due to improper filenames sanitization for uploaded files.
