Drupal 8.1.x < 8.1.10 Multiple Vulnerabilities

Medium

Synopsis

The remote server is hosting an outdated installation of Drupal that is vulnerable to multiple attack vectors.

Description

The version of Drupal installed on the remote server is 8.1.x prior to 8.1.10, and is affected by the following vulnerabilities :

- A flaw exists that is due to the program allowing users who have rights to edit a node to set the visibility for comments on that node. This may allow an authenticated remote attacker to adjust a node's comment visibility preferences without the appropriate privileges. (CVE-2016-7570) - A flaw exists that allows a reflected cross-site scripting (XSS) attack. This flaw exists because the program does not validate input when handling HTTP exception messages before returning it to users. This may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server. (CVE-2016-7571) - A flaw exists related to the 'system.temporary' route that may allow an authenticated remote attacker to download the full config export without the appropriate privileges. This may allow the attacker to gain unauthorized access to sensitive information. (CVE-2016-7572)

Solution

Upgrade to Drupal 8.1.10 or later.
