Background
Drupal is a popular open-source content management system (CMS) used for building websites and applications. The Drupal core package is a fundamental component of Drupal that provides essential functionality and features. This vulnerability affects Drupal versions 8.x before 8.1.10. Drupal allows users to export configuration settings, which can include sensitive information such as database credentials and API keys. However, the system.temporary route in Drupal 8.x before 8.1.10 does not properly check for the 'Export configuration' permission. This oversight allows remote authenticated users to bypass intended access restrictions and read a full config export via unspecified vectors.
Vulnerability Detail
The vulnerability arises from the lack of proper permission checks in the system.temporary route. As a result, authenticated users without the necessary privileges can exploit this flaw to gain access to the full config export. This can lead to unauthorized disclosure of sensitive information, potentially compromising the security and integrity of the affected Drupal installation. The impact of this vulnerability is considered moderate, with a CVSS score of 4.3.
