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 3779985
was released on
13.10.2026 and deals with
"3779985 - [CVE-2026-89117] Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Enterprise Portal" within Java.
We advice you to follow the instructions, to resolve
cross-site scripting (xss)
with a
medium potential for exploitation
in component EP-PIN-URL.
According to SAP Security Advisory team a workaround does not exist. It is advisable to implement the correction as monthly patch process.
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 allows an unauthenticated attacker to inject malicious scripts into a URL parameter, which are reflected in the server response and executed in a victim's browser when the crafted URL is accessed, resulting in unauthorized access to and modification of information within the victim's session.
Solution
Request parameters reflected in the markup are now properly encoded to prevent cross-site scripting.
Affected System
SAP Netweaver Application Server Java is part of the SAP NetWeaver Application Platform. It provides the complete infrastructure for deploying and running Java applications.
