Name: Improper Validation of Specified Type of Input

The product receives input that is expected to be of a certain type, but it does not validate or incorrectly validates that the input is actually of the expected type.

Allgemeine Informationen

Einführungsmodi

Implementation : This weakness can appear in type-unsafe programming languages, or in programming languages that support casting or conversion of an input to another type. If the application itself infers a "type" of input without directly using the types as defined in the language, then this weakness could occur regardless of the programming language.

Anwendbare Plattformen

Sprache

Klasse: Not Language-Specific (Often)

Häufige Konsequenzen

OtherVaries by Context

Hinweis: When input does not comply with the expected type, attackers could trigger unexpected errors, cause incorrect actions to take place, or exploit latent vulnerabilities that would not be possible if the input conformed with the expected type.

Hinweise zur Schwachstellen-Zuordnung

Begründung : 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.
Kommentar : 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.
