Common consequences

What can happen when CWE-1104 is exploited.

Reduce Maintainability, Varies by Context

Affects: Other

Relying on unmaintained components makes it difficult or impossible to fix significant bugs and vulnerabilities, can render code obsolete, and undermine security by complicating maintenance and increasing the risk of new vulnerabilities.

How it happens

When it is introduced

Typically introduced during these phases of the software lifecycle.

How to detect it

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.)

Effectiveness: High

Illustrative examples

Real CVEs that MITRE cites as examples of this weakness.

CVE-2025-40906 — Perl module for BSON serialization includes a component that reached end-of-life approximately five years previously, but has multiple vulnerabilities.
CVE-2024-35252 — Closed-source cloud storage product includes an unmaintained third-party component that allows denial of service
