ID: CVE-2020-6287

Title: SAP NetWeaver Application Server JAVA Multiple Vulnerabilities

Vendor: SAP

Description: SAP NetWeaver AS JAVA (LM Configuration Wizard) 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. An unauthenticated attacker can exploit this vulnerability through the Hypertext Transfer Protocol (HTTP) to take control of trusted SAP applications.
