Advisory

On 13.08.2024 a security relevant correction has been released by SAP SE. The manufacturer resolves an issue within SAP Commerce.

SAP Note 3483256 addresses "[CVE-2024-41735] Cross-Site Scripting (XSS) vulnerability in SAP Commerce Backoffice" to prevent cross-site scripting (xss) with a medium risk for exploitation.

A workaround does exist, according to SAP Security Advisory team. It is advisable to implement the correction as monthly patch process, 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 Backoffice allows an authenticated attacker to attacker to inject malicious script due to insufficiently encoded user controlled inputs in a framework leveraged by the application, resulting in Cross-Site Scripting (XSS) vulnerability.

Solution

SAP Commerce Cloud was updated to now use an updated version of the vulnerable framework that is no longer susceptible to this kind of attack. Circumstances exist that prevent the timely installation of a patch provided by the manufacturer. In such cases, you may consider applying the suggested workaround as a temporary or compensating mitigation: "Cross-site scripting/request forgery filter engine on IDS/IPS/firewall systems. ".
