Insufficient data authenticity validation - Front bypass

Description​

The credentials policy present in the system warns that these cannot be consecutive and/or repeated numbers, however this validation is only done in the front end of the application, so it is possible to modify the password from the same request and assign a key that goes against the policies.

Impact​

Bypass security policies assigned for user keys.

Recommendation​

The key creation policy must be validated on both the front and back ends of the application.

Threat​

Attacker without credentials from the Internet.

Expected Remediation Time​

⌚ 60 minutes.
