Common Weakness Enumeration

CWE-795

Weakness Allowed

Only Filtering Special Elements at a Specified Location

Abstraction: Base · Status: Incomplete

API response cwe.mitre.org

The product receives data from an upstream component, but only accounts for special elements at a specified location, thereby missing remaining special elements that may exist before sending it to a downstream component.

Technical nuance

A filter might only account for instances of special elements when they occur:

relative to a marker (e.g., "at the beginning/end of string; the second argument"), or

at an absolute position (e.g., "byte number 10").

This may leave special elements in the data that did not match the filter position, but still may be dangerous.

Mapping guidance

This CWE entry is at the Base 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.
