CVE-2022-44371Public exploitNetwork attack vector

Unauthenticated code execution via fixed Shiro key

Published Dec 7, 2022 · Updated Apr 23, 2025

Deserialization in hope-boot 1.0.0 allows remote attackers to execute arbitrary code through a crafted Shiro rememberMe cookie. ShiroConfig in the hope-admin module embeds a fixed encryption key, allowing a Commons BeanUtils gadget payload to be encrypted and passed to Shiro for deserialization. The published procedure omits JSESSIONID, and the unauthenticated network path executes the payload in the server process.
