Synopsis

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

Description

SAP NetWeaver Application Server for Java is affected by multiple vulnerabilities, as disclosed in the November SAP Security Patch Day advisory, including the following:

 - SAP NetWeaver AS Java GRMG Heartbeat application version 7.50 allows an unauthenticated attacker to send a crafted request from a vulnerable web application, causing limited impact on confidentiality and integrity of the application. (CVE-2023-42477)

 - SAP NetWeaver AS Java Logon application version 7.50 allows an unauthenticated attacker to brute force the login functionality to identify legitimate user ids. This will have an impact on confidentiality but there is no other impact on integrity or availability. (CVE-2023-42480)

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.
