What the flaw is
SAP NetWeaver Application Server Java Platforms contains a missing authentication for critical function vulnerability allowing unauthenticated access to execute configuration tasks and create administrative users.
CISA's description
SAP NetWeaver AS JAVA (LM Configuration Wizard), versions - 7.30, 7.31, 7.40, 7.50, does not perform an authentication check which allows an attacker without prior authentication to execute configuration tasks to perform critical actions against the SAP Java system, including the ability to create an administrative user, and therefore compromising Confidentiality, Integrity and Availability of the system, leading to Missing Authentication Check.
