Drupal 7.x < 7.80 / 8.9.x < 8.9.14 / 9.x < 9.0.12 / 9.1.x < 9.1.7 XSS (SA-CORE-2021-002)

medium Nessus Plugin ID 148935

Language:

Synopsis

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

Description

According to its self-reported version, the instance of Drupal running on the remote web server is 7.x prior to 7.80, 8.9.x prior to 8.9.14, 9.x prior to 9.0.12, or 9.1.x prior to 9.1.7. It is, therefore, affected by a vulnerability.

- Drupal core's sanitization API fails to properly filter cross-site scripting under certain circumstances.
Not all sites and users are affected, but configuration changes to prevent the exploit might be impractical and will vary between sites. Therefore, we recommend all sites update to this release as soon as possible. (SA-CORE-2021-002)

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 7.80 / 8.9.14 / 9.0.12 / 9.1.7 or later.
