Weakness (CWE)

CWE-74: Injection

Class Incomplete Mapping discouraged Improper Neutralization of Special Elements in Output Used by a Downstream Component

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

How to prevent it (2 mitigations)

  1. Requirements

    Programming languages and supporting technologies might be chosen which are not subject to these issues.

  2. Implementation

    Utilize an appropriate mix of allowlist and denylist parsing to filter control-plane syntax from all input.
