CWE-8 상세 정보

The J2EE application exposes a remote interface for an entity bean, but it also exposes methods that get or set the bean's data.

Phases : Implementation
Declare Java beans "local" when possible. When a bean must be remotely accessible, make sure that sensitive information is not exposed, and ensure that the application logic performs appropriate validation of any data that might be modified by an attacker.

탐지 방법

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.)

취약점 매핑 메모

근거 : 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.
댓글 : 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.

메모

Entity beans that expose a remote interface become part of an application's attack surface. For performance reasons, an application should rarely use remote entity beans, so there is a good chance that a remote entity bean declaration is an error.
