CVE-2021-26295Public exploitNetwork attack vector

Unauthenticated code execution via SOAP object deserialization

Published Mar 22, 2021 · Updated Feb 13, 2025

Unsafe Java deserialization in Apache OFBiz 17.12.01 through 17.12.05 allows remote attackers to execute code via the SOAP endpoint. The SOAP request path passes attacker-supplied serialized objects to SafeObjectInputStream, whose resolveClass method accepted dangerous java.rmi.server classes. No authentication is required, and successful exploitation runs code with the privileges of the OFBiz JVM process, enabling application takeover.
