Drupal 7.x < 7.75 / 8.x < 8.8.12 / 8.9.x < 8.9.10 / 9.0.x < 9.0.9 Multiple Vulnerabilities (SA-CORE-2020-013)

high Nessus Plugin ID 143274

Language:

Synopsis

A PHP application running on the remote web server is affected by multiple vulnerabilities.

Description

According to its self-reported version, the instance of Drupal running on the remote web server is 7.x prior to 7.75, 8.x prior to 8.8.12, 8.9.x prior to 8.9.10, or 9.0.x prior to 9.0.9. It is, therefore, affected by multiple vulnerabilities:

- Archive_Tar through 1.4.10 allows an unserialization attack because phar: is blocked but PHAR: is not blocked. (CVE-2020-28948)

- Archive_Tar through 1.4.10 has :// filename sanitization only to address phar attacks, and thus any other stream-wrapper attack (such as file:// to overwrite files) can still succeed. (CVE-2020-28949)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Drupal version 7.75 / 8.8.12 / 8.9.10 / 9.0.9 or later.
