名前: Weak Encoding for Password

The product uses a weak or trivial encoding for a password.

一般情報

導入モード

Architecture and Design : Password management issues occur when a password is stored in plaintext in an application's properties or configuration file. A programmer can attempt to remedy the password management problem by obscuring the password with an encoding function, such as base64 encoding, but this effort does not adequately protect the password.
Architecture and Design : COMMISSION: This weakness refers to an incorrect design related to an architectural security tactic.

CVE-2022-45099

network attached storage (NAS) product uses weak encoding for a password

潜在的な緩和策

Passwords should be encrypted with keys that are at least 128 bits in length for adequate security.

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.

CAPEC ID 攻撃パターン名
CAPEC-55 Rainbow Table Password Cracking
An attacker gets access to the database table where hashes of passwords are stored. They then use a rainbow table of pre-computed hash chains to attempt to look up the original password. Once the original password corresponding to the hash is obtained, the attacker uses the original password to gain access to the system.
