"SAP NetWeaver Application Server for Java is affected by multiple vulnerabilities:

  - Due to missing authorization check in SAP NetWeaver AS Java (System Landscape Directory) an unauthorized 
    user can read and modify some restricted global SLD configurations causing low impact on confidentiality 
    and integrity of the application. (CVE-2024-42372)

  - SAP NetWeaver AS Java allows an unauthenticated attacker to brute force the login functionality in order 
    to identify the legitimate user IDs. This has an impact on confidentiality but not on integrity or 
    availability. (CVE-2024-47592)

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