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 3748227
was released on
14.07.2026 and deals with
"3748227 - [CVE-2026-44752] Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Application Server Java(Configuration Wizard)" within Java.
We advice you to follow the instructions, to resolve
cross-site scripting (xss)
with a
high potential for exploitation
in component BC-INS-CTC-RT.
According to SAP Security Advisory team a workaround exists. 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 Application Server Java (Configuration Wizard) allows an unauthenticated attacker to inject malicious JavaScript through specially crafted URLs, potentially resulting in the disclosure of sensitive session information when a victim accesses the URL.
Solution
The affected URL parameters are now properly encoded to prevent cross-site scripting (XSS) attacks. Alternativly, the consulting team has proposed the following: "Disabling the application aliases as described in SAP Note 2939665; re-enable temporarily only if required for specific SAP Lifecycle procedures.". 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 8.2 score.
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.
