Description
Due to a CRLF Injection vulnerability in SAP NetWeaver Application Server Java, an authenticated attacker with administrative access could submit specially crafted content to the application.

Successful exploitation leads to a low impact on integrity, while confidentiality and availability remain unaffected.
