Article Details the Shiro Deserialization Vulnerability

The article details the principle of the Shiro deserialization vulnerability. This flaw allows an attacker to deserialize malicious Java objects, which can lead to remote code execution. The vulnerability is exploited through manipulated cookies or HTTP parameters. The impacts include complete server takeover, execution of arbitrary commands, and unauthorized access to data. Unsecured deserialization is at the core of this vulnerability, allowing attackers to inject Java objects that can perform malicious actions upon deserialization.
