SAP NetWeaver Application Server (AS) JAVA is an integrated technology platform that supports the development and execution of Java-based applications in the SAP environment. It provides a range of services, including application server, portal, web services, and business process management.
However, this product is not without its vulnerabilities. The most recent one, CVE-2020-6287, is a missing authentication check vulnerability. This vulnerability allows an attacker without prior authentication to execute configuration tasks and perform critical actions against the SAP Java system. One of these actions is creating an administrative user, which can compromise the Confidentiality, Integrity, and Availability of the system.
When this vulnerability is exploited, it can lead to serious consequences for businesses. Since an attacker can create an administrative user, they have complete control over the SAP Java system. They can access confidential information, modify or delete data, and disrupt business operations, leading to financial loss and reputational damage.
