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 3431794 was released on 14.05.2024 and deals with "[CVE-2024-28165] Cross site scripting vulnerability in SAP BusinessObjects Business Intelligence Platform" within BI/BO platform. We advice you to follow the instructions, to resolve cross-site scripting (xss) with a high potential for exploitation in component BI-BIP-INV.

According to SAP Security Advisory team a workaround exists. It is advisable to implement the correction as part of maintenance.

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 Business Objects Business Intelligence Platform allows an unauthenticated attacker to alter a parameter in the Opendocument URL, causing manipulation of the application's data and settings.

Solution

The risk has been mitigated by sanitizing the user input parameter in the Opendocument URL, which prevents any unauthorized manipulation of the application. Alternativly, the consulting team has proposed the following: "Cross-site scripting/request forgery filter engine on IDS/IPS/firewall systems. ". The suggestion may be considered, as a workaround or compensating mitigation. We recommend installing/applying the correction wherever possible and as soon as possible. Base your decision on whether or not to apply the patch on your companies and systems risk perspective and consider the provided CVSS 8.1 score.
