Advisory

On 11.06.2024 a security relevant correction has been released by SAP SE. The manufacturer resolves an issue within SAP Financial Consolidation.

SAP Note 3457592 addresses "[CVE-2024-37177] Cross-Site Scripting (XSS) vulnerabilities in SAP Financial Consolidation" to prevent Cross-Site Scripting (XSS) with a high risk for exploitation.

A workaround does 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 Financial Consolidation allows an unauthenticated attacker to modify content on the web site and does improper encoding of user controlled inputs resulting in a Cross-Site Scripting (XSS) vulnerability.

Solution

The url parameters are now properly encoded to prevent a successful XSS 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. ".
