CWE-259 (使用硬编码的口令) — Vulnerability Class 126

CWE-259 represents a critical security weakness where software embeds static credentials directly into its source code or configuration for both inbound authentication and outbound communications. Attackers typically exploit this vulnerability by reverse-engineering the application to extract these hardcoded passwords, granting them unauthorized access to sensitive systems or enabling them to impersonate legitimate services during external interactions. This bypasses standard authentication controls, often leading to complete system compromise or data exfiltration. To mitigate this risk, developers must avoid embedding secrets in code entirely. Instead, they should implement robust credential management solutions, such as using secure key vaults, environment variables, or hardware security modules. These approaches ensure that sensitive authentication data remains dynamic, encrypted, and isolated from the application logic, significantly reducing the attack surface and preventing accidental exposure through version control systems or decompiled binaries.
