# Impact :
***********
CWE-287 [ Improper Authentication ]
************************************
Authentication is any process by which a system verifies the identity of a user who wishes
to access it.When an actor claims to have a given identity, the software does not
prove or insufficiently proves that the claim is correct. Improper authentication
occurs when an application improperly verifies the identity of a user.
A software incorrectly validates user's login information and as a result, an attacker can
gain certain privileges within the application or disclose sensitive information that allows
them to access sensitive data and provoke arbitrary code execution.
The weakness is introduced during Architecture and Design, Implementation stages.

CAPEC-115 [ Authentication Bypass ]
*************************************
An attacker gains access to application, service, or device with the privileges
of an authorized or privileged user by evading or circumventing an authentication mechanism.
The attacker is therefore able to access protected data without authentication ever having taken place.
This refers to an attacker gaining access equivalent to an authenticated user without ever going
through an authentication procedure. This is usually the result of the attacker using an unexpected
access procedure that does not go through the proper checkpoints where authentication should occur.
For example, a web site might assume that all users will click through a given link in order to get to
secure material and simply authenticate everyone that clicks the link. However, an attacker might be
able to reach secured web content by explicitly entering the path to the content rather than clicking
through the authentication link, thereby avoiding the check entirely. This attack pattern differs from
other authentication attacks in that attacks of this pattern avoid authentication entirely, rather than
faking authentication by exploiting flaws or by stealing credentials from legitimate users.
