Advisory
A note with CVSS 6.1 for component EP-PIN-GPA was released by SAP on 12.07.2022. The correction/advisory 3210779 was described with "[CVE-2022-35224] Cross-Site Scripting (XSS) vulnerability in SAP Enterprise Portal" and affects the system type Java.
A workaround exists, 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 Java.
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 NetWeaver Enterprise Portal does not sufficiently encode user-controlled inputs resulting in a Cross-Site Scripting attack.Solution
The URL parameters are now properly encoded to prevent a successful XSS attack. Although an alternative solution exists, it is advisable to apply the correction! This is the workaround, which was suggested by the SAP security experts: "Cross-site scripting/request forgery filter engine on IDS/IPS/firewall systems. ".
