"Multiple vulnerabilities may be present in SAP NetWeaver Application Server ABAP, including the following:

  - Due to insufficient input validation, SAP NetWeaver Application Server ABAP and ABAP Platform allows an
    attacker with high level privileges to use a remote enabled function to delete a file which is otherwise
    restricted. On successful exploitation an attacker can completely compromise the integrity and availability
    of the application. (CVE-2022-41214)

  - Due to insufficient input validation, SAP NetWeaver Application Server ABAP and ABAP Platform allows an
    attacker with high level privileges to use a remote enabled function to read a file which is otherwise
    restricted. On successful exploitation an attacker can completely compromise the confidentiality of the
    application. (CVE-2022-41212)

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