Name of the Vulnerable Software and Affected Versions: SAP NetWeaver versions 700 through 730

Description: The issue arises from insufficient encoding of user-controlled inputs, allowing an attacker to cause a potential victim to supply malicious content to a vulnerable web application. This content is then reflected to the victim and executed by the web browser, resulting in a Cross-Site Scripting issue.

Recommendations: For SAP NetWeaver versions 700 through 730, consider implementing proper input encoding to prevent malicious content from being executed by the web browser. As a temporary workaround, restrict access to user-controlled input fields to minimize the risk of exploitation.
