CAPEC-251 Metadata
Likelihood of Attack
High
Typical Severity
Medium
Overview
Summary
The attacker forces an application to load arbitrary code files from the local machine. The attacker could use this to try to load old versions of library files that have known vulnerabilities, to load files that the attacker placed on the local machine during a prior attack, or to otherwise change the functionality of the targeted application in unexpected ways.
Prerequisites
The targeted application must have a bug that allows an adversary to control which code file is loaded at some juncture. Some variants of this attack may require that old versions of some code files be present and in predictable locations.
Potential Solutions / Mitigations
Implementation: Avoid passing user input to filesystem or framework API. If necessary to do so, implement a specific, allowlist approach.

Related CAPECs
| CAPEC ID | Description |
|---|---|
| CAPEC-175 | An adversary exploits a weakness on the target to force arbitrary code to be retrieved locally or from a remote location and executed. This differs from code injection in that code injection involves the direct inclusion of code while code inclusion involves the addition or replacement of a reference to a code file, which is subsequently loaded by the target and used as part of the code of some application. |
