CVE-2025-42878Network attack vector

Data exposure and service disruption via testing interfaces

Published Dec 9, 2025 · Updated Dec 9, 2025

Unsafe testing-interface exposure in SAP Web Dispatcher and ICM allows remote attackers to access diagnostics and disrupt services. The internal testing interfaces, when enabled in production, expose diagnostic functions without authentication and process crafted requests outside their intended test context. Exploitation requires network access, an enabled interface, and user interaction; successful requests can disclose diagnostics, affect request handling, and interrupt service.
