Synopsis

The remote SAP NetWeaver application server is affected by a missing authentication vulnerability.

Description

The version of the SAP NetWeaver kernel detected on the remote host is affected by a missing authentication vulnerability as referenced in SAP Security Note 3759472:

- SAP NetWeaver Message Server does not sufficiently validate the authenticity of internal application server components during registration. An unauthenticated attacker with network access to the affected service could exploit this weakness to register an unauthorized component and potentially perform unauthorized actions within the application environment, resulting in a high impact on the confidentiality, integrity, and availability of the affected system. (CVE-2026-58240)
