CWE-257: Storing Passwords in a Recoverable Format
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The storage of passwords in a recoverable format makes them subject to password reuse attacks by malicious users. In fact, it should be noted that recoverable encrypted passwords provide no significant benefit over plaintext passwords since they are subject not only to reuse by malicious attackers but also by malicious insiders. If a system administrator can recover a password directly, or use a brute force search on the available information, the administrator can use the password on other accounts.
常见后果
影响范围: Confidentiality Access Control
技术影响: Gain Privileges or Assume Identity
说明: User's passwords may be revealed.
影响范围: Access Control
技术影响: Gain Privileges or Assume Identity
说明: Revealed passwords may be reused elsewhere to impersonate the users in question.
潜在缓解措施
阶段: Architecture and Design
描述: Use strong, non-reversible encryption to protect stored passwords.
检测方法
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.)
有效性: High
观察示例
