CVE-2017-3506Known exploitationNetwork attack vector

Unauthenticated code execution via SOAP XML deserialization

Published Apr 24, 2017 · Updated Oct 21, 2025

XML deserialization in Oracle WebLogic Server Web Services allows remote attackers to execute code via crafted HTTP requests. The wls-wsat endpoint processes attacker-controlled SOAP WorkContext XML through XMLDecoder, invoking objects and methods specified in the request. No credentials or user interaction are required; affected releases are 10.3.6.0, 12.1.3.0, 12.2.1.0, 12.2.1.1 and 12.2.1.2, with data access bounded by server permissions.
