This is a Python script for exploiting a vulnerability in Apache Shiro, a Java-based security framework. The script is designed to bypass authentication and authorization checks in Shiro, allowing an attacker to gain unauthorized access to sensitive data.
The script uses the `Crypto.Cipher` module to perform AES-GCM encryption and decryption, and it includes a list of possible Shiro keys that can be used for exploitation.
The script has two main functions: `gcm_decode` and `gcm_encode`. The `gcm_decode` function takes a base64-encoded string as input, decrypts it using the AES-GCM algorithm, and returns the decrypted plaintext. The `gcm_encode` function takes a plaintext string as input, encrypts it using the AES-GCM algorithm, and returns the encrypted ciphertext.
The script also includes a list of possible Shiro keys, which can be used for exploitation. These keys are hardcoded in the script and can be used to bypass authentication and authorization checks in Shiro.
The script is designed to be used with the `ysoserial` tool, which is a Java-based tool for creating malicious serialized Java objects. The script can be used to create a malicious serialized Java object that can be used to exploit the Shiro vulnerability.
Overall, this script is a tool
