- Likelihood: Medium (Misconfiguration of TLS is common, especially if defaults are not secure or admins lack TLS knowledge).
- Impact: Critical (Man-in-the-middle attacks, decryption, data interception).
- Effort: Low to Medium (Tools to test TLS configurations are readily available, exploiting weak ciphers might require more effort).
- Skill Level: Beginner to Intermediate (Misconfiguration), Intermediate to Advanced (Exploitation).
