CVE-2022-45378Network attack vector

Conditional code execution via unauthenticated RPC invocation

Published Nov 14, 2022 · Updated Aug 3, 2024

Missing authentication in Apache SOAP 2.3 allows remote attackers to invoke eligible classpath methods through RPCRouterServlet. The servlet is exposed without authentication in the default server configuration and dispatches attacker-selected RPC calls to classes that satisfy its invocation criteria. Code execution requires a suitable method on the deployed classpath; otherwise, the exposure is limited to callable methods and their application-specific effects.
