Background
Ninja Core is a Java web framework designed to simplify the development of web applications. It provides a range of features including dependency injection, routing, and templating. However, a vulnerability has been identified in version 7.0.0 of Ninja Core, where the encrypt() function employs a weak cryptographic algorithm, potentially exposing sensitive information.
Vulnerability Detail
The vulnerability arises from the use of a weak cryptographic algorithm in the encrypt() function of Ninja Core v7.0.0. This flaw can lead to the leakage of sensitive information, as the encryption may be easily compromised by attackers. The issue is classified under CWE-326, which pertains to the use of inadequate cryptographic algorithms. If exploited, this vulnerability could result in unauthorized access to confidential data, posing significant risks to users and applications relying on this framework.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As a temporary workaround, developers can replace the encrypt() function with a more secure encryption method, such as AES (Advanced Encryption Standard). Here is an example of how to implement AES encryption in Java:
import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
public class EncryptionUtil { private static final String ALGORITHM = "AES";
public static byte[] encrypt(String data, SecretKey key) throws Exception {
Cipher cipher =
Cipher.getInstance(ALGORITHM);
cipher.init(Cipher.ENCRYPT_MODE, key);
return cipher.doFinal(data.getBytes());
}
public static SecretKey generateKey() throws Exception {
KeyGenerator keyGen =
KeyGenerator.getInstance(ALGORITHM);
keyGen.init(128);
// or 256 for stronger encryption
return keyGen.generateKey();
}
}
Conclusion
In summary, CVE-2024-36823 highlights a significant vulnerability in Ninja Core v7.0.0 due to the use of weak encryption. It is crucial for developers to update to a patched version or implement secure encryption methods to safeguard sensitive information.
