Synopsis

The remote SAP NetWeaver application server is affected by multiple vulnerabilities.

Description

SAP NetWeaver Application Server for Java is affected by multiple vulnerabilities, including the following:

- A critical vulnerability in SAP NetWeaver Application server for Java Log Viewer enables authenticated administrator users to exploit unsafe Java object deserialization. Successful exploitation can lead to full operating system compromise, granting attackers complete control over the affected system.
(CVE-2025-42963)

- The widely used component that establishes outbound TLS connections in SAP NetWeaver Application Server Java does not reliably match the hostname that is used for the connection against the wildcard hostname defined in the received certificate of remote TLS server. This might lead to the outbound connection being established to a possibly malicious remote TLS server and hence disclose information. (CVE-2025-42978)

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.
