Nom: Missing Critical Step in Authentication

The product implements an authentication technique, but it skips a step that weakens the technique.

Description du CWE

Authentication techniques should follow the algorithms that define them exactly, otherwise authentication can be bypassed or more easily subjected to brute force attacks.

Informations générales

Modes d'introduction

Implementation : REALIZATION: This weakness is caused during implementation of an architectural security tactic.

Plateformes applicables

Langue

Class: Not Language-Specific (Undetermined)

Conséquences courantes

Portée Impact Probabilité
Access Control
Integrity
Confidentiality
Bypass Protection Mechanism, Gain Privileges or Assume Identity, Read Application Data, Execute Unauthorized Code or Commands

Note: This weakness can lead to the exposure of resources or functionality to unintended actors, possibly providing attackers with sensitive information or allowing attackers to execute arbitrary code.

Exemples observés

Références Description

CVE-2004-2163

Shared secret not verified in a RADIUS response packet, allowing authentication bypass by spoofing server replies.

CVE-2005-3327

Chain: Authentication bypass by skipping the first startup step as required by the protocol.

Méthodes de détection

Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
Efficacité : High

Notes de cartographie des vulnérabilités

Justification : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Commentaire : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
