[Security] Potential Insecure Use of Key as IV in Encryption Function

[kexinoh]

Description

While reviewing the antSword-shells/jsp_custom_script_for_oracle.jsp file, a security concern has been identified at line 414. The code in question may be exploitable if not handled correctly.

Steps to Reproduce

1. Access the antSword-shells/jsp_custom_script_for_oracle.jsp file in the repository.
2. Navigate to line 414 to review the code in question.

Expected Behavior

The encryption function should use a unique and unpredictable IV (Initialization Vector) for each encryption operation to ensure the security of the encrypted data.

Actual Behavior

The encryption function is using a static key as an IV, which can be exploited to potentially break the encryption.

Impact

Using a static IV can lead to serious security vulnerabilities, allowing attackers to perform various attacks.

Suggested Solution

It is recommended to generate a new, random IV for each encryption operation and ensure it is transmitted along with the encrypted data, if necessary. This would align with best practices for secure encryption.
