Synopsis

The remote SAP NetWeaver application server is affected by a denial of service vulnerability.

Description

The version of SAP NetWeaver Application Server for Java detected on the remote host is affected by a denial of service vulnerability as disclosed in the SAP Security Patch Day December 2025:

- SAP NetWeaver remote service for Xcelsius allows an attacker with network access and high privileges to execute arbitrary code on the affected system due to insufficient input validation and improper handling of remote method calls. Exploitation does not require user interaction and could lead to service disruption or unauthorized system control. This has high impact on integrity and availability, with no impact on confidentiality. (CVE-2025-42874)

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

Solution

Apply the appropriate patch according to the vendor advisory.
