Code Injection in SAP NetWeaver Java Enables Client-Side Attack

Publication date: 2026-04-14

Last updated on: 2026-06-03

Assigner: SAP SE

Description

Due to a Code Injection vulnerability in SAP NetWeaver Application Server Java (Web Dynpro Java), an unauthenticated attacker could supply crafted input that is interpreted by the application and causes it to reference attacker-controlled content. If a victim accesses the affected functionality, that attacker-controlled content could be executed in the victim�s browser, potentially resulting in session compromise. This could allow the attacker to execute arbitrary client-side code, impacting the confidentiality and integrity of the application, with no impact to availability.

Attack-Flow Graph

Executive Summary

This vulnerability is a Code Injection issue in SAP NetWeaver Application Server Java (Web Dynpro Java). An unauthenticated attacker can supply specially crafted input that the application interprets in a way that causes it to reference content controlled by the attacker.

If a victim accesses the affected functionality, the attacker-controlled content could be executed in the victim's browser, potentially leading to session compromise.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary client-side code in the victim's browser.

This impacts the confidentiality and integrity of the application by potentially compromising user sessions.

There is no impact on the availability of the application.

Compliance Impact

This vulnerability could impact the confidentiality and integrity of the application by allowing an attacker to execute arbitrary client-side code and potentially compromise user sessions.

Such impacts on confidentiality and integrity may lead to non-compliance with standards and regulations like GDPR and HIPAA, which require protection of sensitive data and secure handling of user information.

However, the provided information does not explicitly state the direct effects on compliance with these standards.
