名前: Missing Critical Step in Authentication

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

一般情報

背景の詳細

導入モード

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

適用可能なプラットフォーム

言語

クラス: Not Language-Specific (Undetermined)

一般的な結果

スコープ 影響 可能性
Access Control
Integrity
Confidentiality
Bypass Protection Mechanism, Gain Privileges or Assume Identity, Read Application Data, Execute Unauthorized Code or Commands

注記: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.

参考文献 説明

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.

検出方法

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.)
有効性 : High

脆弱性マッピングノート

理由 : 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.
コメント : 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.
