Advisory

A note with CVSS 4.8 for component CA-FLP-ABA was released by SAP on 08.09.2020. The correction/advisory 2865229 was described with "[CVE-2020-6283] Cross-Site Scripting (XSS) vulnerability in SAP Fiori(Launchpad)" and affects the system type SAP UI5.

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

The vulnerability addressed is Cross-Site Scripting (XSS) within SAP UI5.

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 Fiori Launchpad does not sufficiently encode user controlled inputs, allowing the attacker to inject the meta tag into the launchpad HTML using the vulnerable parameter, resulting in reflected Cross-Site Scripting (XSS) vulnerability.

Solution

SAP Fiori Launchpad now properly encodes user provided input, preventing this type of attack.

The advisory is valid for

SAP_UI 750 ¹⁸
SAP_UI 752 ⁸
SAP_UI 753 ¹⁸
