How the Exploit Works

The vulnerability exists in the EncryptionUtil class where symmetric encryption is implemented in a deterministic and non-randomized fashion. The encryption key and the IV (Initialization Vector) are derived from a fixed, hardcoded input using a static salt value. Consequently, identical plaintext inputs will always produce identical ciphertext outputs, for both FIPS and non-FIPS generated passwords. This results in predictable and reversible encrypted outputs due to the lack of per-operation randomness and encryption authentication.

Conceptual Example Code

The following pseudocode offers a conceptual example of how the vulnerability might be exploited:

def exploit(target):
plaintext_password = "admin"
encrypted_password = EncryptionUtil.Encrypt(plaintext_password)
# As the encryption is deterministic, the encrypted_password will always be the same.
# An attacker can use this predictable output to their advantage.
login(target, encrypted_password)

This pseudocode illustrates the deterministic nature of the encryption used and how it could be exploited to gain unauthorized access.
