SAP NetWeaver Java UI Redressing via Styling Resource

Publication date: 2026-11-10

Last updated on: 2026-11-10

Assigner: SAP SE

Description
SAP NetWeaver Application Server Java (Web Dynpro Java) does not sufficiently validate certain request parameters used to resolve styling resources in the application. An unauthenticated attacker could craft a malicious link that, when clicked by an authenticated victim, causes the victim's browser to load attacker-controlled styling content within the trusted application context. Successful exploitation could allow the attacker to redress the trusted user interface for phishing purposes and exfiltrate limited web page content, resulting in a low impact on confidentiality and integrity. There is no impact on availability.

Executive Summary

SAP NetWeaver Application Server Java (Web Dynpro Java) fails to properly validate request parameters used for styling resources. An attacker can create a malicious link that, when clicked by an authenticated user, loads attacker-controlled styling content within the trusted application. This could allow phishing attacks and limited data exfiltration.

Detection Guidance

Detecting this vulnerability requires monitoring for unusual request parameters in SAP NetWeaver Application Server Java (Web Dynpro Java). Check web server logs for suspicious URLs containing styling resource parameters. Use network traffic analysis tools to inspect HTTP requests for unexpected or malformed parameters targeting styling resources.

Impact Analysis

An attacker could trick you into clicking a malicious link, making the application appear legitimate while stealing limited data or tricking you into entering sensitive information. This could lead to phishing attacks or unauthorized data access.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, potentially violating GDPR (data protection) or HIPAA (health data privacy) by exposing sensitive user information. Organizations must address it to maintain compliance.

Mitigation Strategies
  • Apply the latest security patches provided by SAP for SAP NetWeaver Application Server Java.
  • Review and restrict access to Web Dynpro Java applications to trusted users only.
  • Monitor network traffic for suspicious requests targeting styling resources in Web Dynpro Java.
  • Educate users to avoid clicking on untrusted links, especially those requesting styling resources.
