Business Risk
By exploiting this vulnerability, an internal or external attacker will be able to escalate their privileges. With the help of this access, it is possible to obtain sensitive technical and business-related information stored in the vulnerable SAP system.

An SQL injection vulnerability means that the code comprises an SQL statement that contains strings that can be altered by an attacker. The manipulated SQL statement can then be used to retrieve additional data from the database, or to modify the data.
