Vulnerability Title
SQL Injection Vulnerability in SAP NetWeaver (Feedback Notification)
Source: CVE Program / CVE List V5
Vulnerability Description
SAP NetWeaver Feedback Notifications Service contains a SQL injection vulnerability that allows an authenticated attacker to inject arbitrary SQL code through user-controlled input fields. The application concatenates these inputs directly into SQL queries without proper validation or escaping. As a result, an attacker can manipulate the WHERE clause logic and potentially gain unauthorized access to or modify database information. This vulnerability has no impact on integrity and low impact on the confidentiality and availability of the application.
