Drupal 8.3.x < 8.3.0-rc2 Multiple Vulnerabilities

According to its self-reported version number, the detected Drupal application is affected by multiple vulnerabilities :

• A security bypass vulnerability exists in the editor module due to a failure to properly check access restrictions when adding private files with a configured text editor (e.g. CKEDITOR). An unauthenticated, remote attacker can exploit this to bypass access restrictions and disclose arbitrary files. (CVE-2017-6377)

• A cross-site request forgery (XSRF) vulnerability exists as HTTP requests do not require multiple steps, explicit confirmation, or a unique token when performing certain sensitive actions. An unauthenticated, remote attacker can exploit this, by convincing a user to follow a specially crafted link, to cause the user to disable some blocks on sites or perform additional unintended actions. (CVE-2017-6379)

• An unspecified flaw exists in the PHPUnit component that allows an unauthenticated, remote attacker to execute arbitrary code. Note that this vulnerability may only impact versions prior to 8.2.2. (CVE-2017-6381)

Note that the scanner has not tested for these issues but has instead relied only on the application’s self-reported version number.
