SAP NetWeaver AS Missing Authorization Check (September 2021)

critical Nessus Plugin ID 153441

Synopsis

The remote SAP NetWeaver server is missing an authorization check.

Description

The version of SAP NetWeaver AS installed on the remote host may not perform necessary authorization checks for user privileges, and this can be exploited by a remote, unauthenticated attacker.

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