Advisory

SAP takes the security of its vast product portfolio very seriously and thus releases security fixes for vulnerabilities reported by external researchers and their customers every second Tuesday of the month.

SAP Note 2606194 was released on 09.09.2020 and deals with "Cross-Site Scripting (XSS) vulnerability in CRM Interaction Center" within ABAP. We advice you to follow the instructions, to resolve Cross-Site Scripting (XSS) with a medium potential for exploitation in component CRM-IC-FRW.

According to SAP Security Advisory team a workaround does not exist. It is advisable to implement the correction as monthly patch process.

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

The WebUI in SAP CRM Interaction Center is the central interface for internal agents to process and document customer requests. User inputs are not sufficiently encoded, which leaves the option for authenticated attackers to exploit a Cross-Site Scripting (XSS) vulnerability.

Solution

Company name / contact name in context area are now properly encoded to prevent a XSS attach.
