Advisory

A note with CVSS 6.1 for component BC-XI-IBF-WU was released by SAP on 08.08.2023. The correction/advisory 3350494 was described with "[CVE-2023-37488] Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Process Integration" 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 NetWeaver Process Integration does not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability.

Solution

The respective input/output encoding has been added, preventing a successful reflected 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. ".

Affected System

SAP Netweaver Application Server Java is part of the SAP NetWeaver Application Platform. It provides the complete infrastructure for deploying and running Java applications.
