CWE-1104 (使用未维护的第三方组件) — Vulnerability Class 22

CWE-1104 represents a supply chain weakness where software dependencies rely on third-party components that lack active maintenance or security support from their original developers. This vulnerability is typically exploited by threat actors who identify known, unpatched flaws within these obsolete libraries, leveraging them to execute remote code injection, data exfiltration, or privilege escalation attacks. Because unmaintained components cease receiving security updates, they become persistent entry points for adversaries seeking to bypass modern defenses. To mitigate this risk, developers must implement rigorous dependency management practices, including regular automated audits to identify outdated packages and establish strict policies for replacing unsupported libraries with actively maintained alternatives. Continuous monitoring of vulnerability databases and integrating software composition analysis tools into the CI/CD pipeline further ensures that only secure, current components are integrated into the final product, thereby reducing the attack surface associated with legacy code.
