CVE-2022-28772Network attack vector

Remote service crash via stack overwrite

Published Apr 12, 2022 · Updated Aug 3, 2024

Stack-based buffer overflow in SAP Web Dispatcher and Internet Communication Manager allows remote attackers to crash affected services. Request-processing code accepts overlong input values and overwrites the internal program stack; SAP has not identified the field or routine. No authentication or user interaction is required, and successful exploitation makes the targeted service unavailable without reported data disclosure or modification.
