Advisory

On 08.06.2021 a security relevant correction has been released by SAP SE. The manufacturer resolves an issue within SAP Commerce Cloud.

SAP Note 2985562 addresses "[CVE-2021-33666] Cross-Site Scripting (XSS) in SAP Commerce Cloud" to prevent cross-site scripting (xss) with a medium risk for exploitation.

A workaround does not exist, according to SAP Security Advisory team. It is advisable to implement the correction as part of maintenance, the team suggests.

Cross-site scripting (XSS) is the name of a class of security vulnerabilities that can occur in web-based applications. XSS combines all vulnerabilities that allow an attacker to inject HTML Markup and/or JavaScript into the front end of the affected web application.

XSS attacks can occur whenever the application dynamically creates its HTML/JavaScript/CSS content, which is passed to the user's web browser, and attacker-controlled values are used in this process. If these values are included in the generated code without proper validation and encoding, the attacker is able to include arbitrary coding snippets into the application's front end. The code is then rendered by the victim's web browser and interpreted in the victim's current authentication context.

Risk specification

SAP Commerce Cloud environments that include a JavaScript storefront (in particular Spartacus)) allow an unauthenticated attacker through MIME sniffing vulnerability to facilitate XSS attacks or malware proliferation.

Solution

The vulnerability was addressed by adding an X-Content-Type-Options HTTP response header with the value 'nosniff' with all requested resources of the JavaScript Storefront.

The advisory is valid for

  • CX_COMM_CLOUD_AUTO 100
