SAP NetWeaver AS Java Code Injection (3719397)

medium Nessus Plugin ID 306733

Synopsis

The remote SAP NetWeaver AS Java server is affected by a code injection vulnerability.

Description

The version of SAP NetWeaver Application Server Java detected on the remote host is affected by a code injection vulnerability as disclosed in the SAP Security Patch Day April 2026:

- 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. (CVE-2026-27674)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the appropriate patch according to the vendor advisory.
