SAP AS JAVA (Key Storage Service), versions - 7.10, 7.11, 7.20 ,7.30, 7.31, 7.40, 7.50, has the key material which is stored in the SAP NetWeaver AS Java Key Storage service stored in the database in the DER encoded format and is not encrypted. This enables an attacker who has administrator access to the SAP NetWeaver AS Java to decode the keys because of missing encryption and get some application data and client credentials of adjacent systems. This highly impacts Confidentiality as information disclosed could contain client credentials of adjacent systems.
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

Because the information is stored in cleartext (i.e., unencrypted), attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information. When organizations adopt cloud services, it can be easier for attackers to access the data from anywhere on the Internet. In some systems/environments such as cloud, the use of “double encryption” (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
