Security

$METHOD is a state-changing MVC method that does not validate the antiforgery token or do strict content-type checking. State-changing controller methods should either enforce antiforgery tokens or do strict content-type checking to prevent simple HTTP request types from bypassing CORS preflight controls.
Likelihood: LOW
Confidence: LOW
CWE:
- CWE-352: Cross-Site Request Forgery (CSRF)
OWASP:
- A01:2021 - Broken Access Control

Cookie Secure flag is explicitly disabled. You should enforce this value to avoid accidentally presenting sensitive cookie values over plaintext HTTP connections.
Likelihood: LOW
Confidence: LOW
CWE:
- CWE-614: Sensitive Cookie in HTTPS Session Without ‘Secure’ Attribute
OWASP:
- A05:2021 - Security Misconfiguration

You are using the outdated PKCS#1 v1.5 encryption padding for your RSA key. Use the OAEP padding instead.
Likelihood: HIGH
Confidence: MEDIUM
CWE:
- CWE-780: Use of RSA Algorithm without OAEP
OWASP:
- A02:2021 - Cryptographic Failures

You are using an insecure random number generator (RNG) to create a cryptographic key. System.Random must never be used for cryptographic purposes. Use System.Security.Cryptography.RandomNumberGenerator instead.
Likelihood: HIGH
Confidence: HIGH
CWE:
- CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)
OWASP:
- A02:2021 - Cryptographic Failures

Usage of the insecure ECB mode detected. You should use an authenticated encryption mode instead, which is implemented by the classes AesGcm or ChaCha20Poly1305.
Likelihood: HIGH
Confidence: HIGH
CWE:
- CWE-327: Use of a Broken or Risky Cryptographic Algorithm
OWASP:
- A02:2021 - Cryptographic Failures

OWASP guidance recommends disabling tracing for production applications to prevent accidental leakage of sensitive application information.
