Drupal 7.x < 7.67 / 8.6.x < 8.6.16 / 8.7.x < 8.7.1 (SA-CORE-2019-007)

critical Nessus Network Monitor Plugin ID 700664

Synopsis

A PHP application running on the remote web server is affected by a path traversal vulnerability.

Description

According to its self-reported version, the instance of Drupal running on the remote web server is 7.0.x prior to 7.67, 8.6.x prior to 8.6.x, or 8.7.x prior to 8.7.1. It is, therefore, affected by a path traversal vulnerability. This security release fixes third-party dependencies included in or required by Drupal core.
As described in TYPO3-PSA-2019-007: By-passing protection of Phar Stream Wrapper Interceptor: In order to intercept file invocations like file_exists or stat on compromised Phar archives the base name has to be determined and checked before allowing to be handled by PHP Phar stream handling. The current implementation is vulnerable to path traversal leading to scenarios where the Phar archive to be assessed is not the actual (compromised) file.

Solution

Upgrade to Drupal 8.7.1, or later. If 8.7.x cannot be obtained, 8.6.16 and 7.67 have also been patched for this vulnerability.
