Advisory

A note with CVSS 5.4 for component BI-BIP-INV was released by SAP on 14.09.2021. The correction/advisory 3055180 was described with "[CVE-2021-33679] Cross-Site Scripting (XSS) vulnerability in SAP BusinessObjects Business Intelligence Platform (BI Workspace)" and affects the system type BI/BO platform.

A workaround does not exist, 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 BI/BO platform.

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 BusinessObjects BI Platform allows an authenticated attacker to inject malicious script while creating a new module document, file, or folder. The stored malicious script will be executed when other user visits the page allowing the attacker to compromise their confidentiality and integrity.

Solution

The affected BI application has been strengthened by implementing the Support Packages & Patches mentioned in the note.
