Common Weakness Enumeration

CWE-105

Weakness Allowed

Struts: Form Field Without Validator

Abstraction: Variant · Status: Draft

The product has a form field that is not validated by a corresponding validation form, which can introduce other weaknesses related to insufficient input validation.

Mapping guidance

This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.

Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Modes of introduction
Implementation

Some products use the same ActionForm for more than one purpose. In situations like this, some fields may go unused under some action mappings.

Detection methods

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.)

0 vulnerabilities reference this CWE, most recent first.

No vulnerabilities reference this CWE.

Mitigation
Implementation

Validate all form fields. If a field is unused, it is still important to constrain it so that it is empty or undefined.

No CAPEC attack patterns related to this CWE.
