The versions of Oracle Siebel CRM installed on the remote host are affected by multiple vulnerabilities as referenced in the April 2023 CPU advisory.

  - Vulnerability in the Siebel CRM product of Oracle Siebel CRM (component: Open UI (CKEditor)). Supported     versions that are affected are 21.10 and prior. Easily exploitable vulnerability allows low privileged     attacker with network access via HTTP to compromise Siebel CRM. Successful attacks require human     interaction from a person other than the attacker and while the vulnerability is in Siebel CRM, attacks     may significantly impact additional products (scope change). Successful attacks of this vulnerability can     result in unauthorized update, insert or delete access to some of Siebel CRM accessible data as well as     unauthorized read access to a subset of Siebel CRM accessible data. (CVE-2021-32808, CVE-2021-32809,     CVE-2021-37695)

According to its self-reported version, the instance of Drupal running on the remote web server is 8.9.x prior to 8.9.18, 9.1.x prior to 9.1.12, or 9.2.x prior to 9.2.4. It is, therefore, affected by multiple vulnerabilities due to its usage of a third party component, CKEditor, for WYSIWYG editing:

 - A vulnerability was discovered in CKEditor 4 Fake Objects package. The vulnerability allowed to inject malformed Fake Objects HTML, which could result in executing JavaScript code. (CVE-2021-37695)

 - A vulnerability was discovered in the clipboard Widget plugin if used alongside the undo feature. The vulnerability allows a user to abuse undo functionality using malformed widget HTML, which could result in executing JavaScript code. (CVE-2021-32808)

 - A vulnerability was discovered in CKEditor 4 Clipboard package. The vulnerability allowed to abuse paste functionality using malformed HTML, which could result in injecting arbitrary HTML into the editor. (CVE-2021-32809)
