CVE-2022-21445Known exploitationPublic exploitNetwork attack vector

Unauthenticated code execution via ViewState deserialization

Published Apr 19, 2022 · Updated Oct 21, 2025

Deserialization in Oracle ADF Faces 12.2.1.3.0 and 12.2.1.4.0 allows remote attackers to execute arbitrary code via HTTP. The ADF Faces request path deserializes attacker-controlled JSF ViewState data, allowing a classpath gadget chain to run code. No authentication or user interaction is required; compromise of a reachable ADF Faces application permits application takeover.
