Advisory

A note with CVSS 6.1 for component EP-PIN-WPC was released by SAP on 12.07.2022. The correction/advisory 3211760 was described with "[CVE-2022-35227] Cross-Site Scripting (XSS) vulnerability in SAP NW EP WPC" and affects the system type Java.

A workaround exists, according to SAP Security Advisory team. It is advisable to implement the correction as part of maintenance.

The vulnerability addressed is cross-site scripting (xss) within Java.

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 NW EP WPC does not sufficiently encode user-controlled inputs resulting in a Cross-Site Scripting attack.

Solution

The URL parameters are now properly encoded to prevent a successful XSS attack. Although an alternative solution exists, it is advisable to apply the correction! This is the workaround, which was suggested by the SAP security experts: "Cross-site scripting/request forgery filter engine on IDS/IPS/firewall systems. ".
