  34. # Impact :
  35. ***********
  36. CWE-284 [ Improper Access Control ]
  37.  
  38. The software does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
  39.  
  40. CWE-287 [ Improper Authentication ]
  41.  
  42. Authentication is any process by which a system verifies the identity of a user who wishes
  43. to access it.When an actor claims to have a given identity, the software does not
  44. prove or insufficiently proves that the claim is correct. Improper authentication
  45. occurs when an application improperly verifies the identity of a user.
  46. A software incorrectly validates user's login information and as a result, an attacker can
  47. gain certain privileges within the application or disclose sensitive information that allows
  48. them to access sensitive data and provoke arbitrary code execution.
  49. The weakness is introduced during Architecture and Design, Implementation stages.
  50.  
  51. CAPEC-115 [ Authentication Bypass ]
  52.  
  53. An attacker gains access to application, service, or device with the privileges
  54. of an authorized or privileged user by evading or circumventing an authentication mechanism.
  55. The attacker is therefore able to access protected data without authentication ever having taken place.
  56. This refers to an attacker gaining access equivalent to an authenticated user without ever going
  57. through an authentication procedure. This is usually the result of the attacker using an unexpected
  58. access procedure that does not go through the proper checkpoints where authentication should occur.
  59. For example, a web site might assume that all users will click through a given link in order to get to
  60. secure material and simply authenticate everyone that clicks the link. However, an attacker might be
  61. able to reach secured web content by explicitly entering the path to the content rather than clicking
  62. through the authentication link, thereby avoiding the check entirely. This attack pattern differs from
  63. other authentication attacks in that attacks of this pattern avoid authentication entirely, rather than
  64. faking authentication by exploiting flaws or by stealing credentials from legitimate users.
