"SAP NetWeaver Application Server for ABAP is affected by NULL pointer dereference vulnerability:

  - SAP NetWeaver Application Server for ABAP and ABAP Platform allows an unauthenticated attacker to send a 
    maliciously crafted http request which could cause a null pointer dereference in the kernel. This 
    dereference will result in the system crashing and rebooting, causing the system to be temporarily 
    unavailable. There is no impact on Confidentiality or Integrity. (CVE-2024-47586)

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