"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.");
