CWE-539: Use of Persistent Cookies Containing Sensitive Information
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The web application uses persistent cookies, but the cookies contain sensitive information.
扩展描述
Cookies are small bits of data that are sent by the web application but stored locally in the browser. This lets the application use the cookie to pass information between pages and store variable information. The web application controls what information is stored in a cookie and how it is used. Typical types of information stored in cookies are session identifiers, personalization and customization information, and in rare cases even usernames to enable automated logins. There are two different types of cookies: session cookies and persistent cookies. Session cookies just live in the browser's memory and are not stored anywhere, but persistent cookies are stored on the browser's hard drive. This can cause security and privacy issues depending on the information stored in the cookie and how it is accessed.
常见后果
影响范围: Confidentiality
技术影响: Read Application Data
潜在缓解措施
阶段: Architecture and Design
描述: Do not store sensitive information in persistent cookies.
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.)
