導入モード
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.

可能性 |
| Integrity | Unexpected State
注記:Omitting validation for even a single input field may give attackers the leeway they need to compromise the product. Although J2EE applications are not generally susceptible to memory corruption attacks, if a J2EE application interfaces with native code that does not perform array bounds checking, an attacker may be able to use an input validation mistake in the J2EE application to launch a buffer overflow attack. | |
| Integrity | Bypass Protection Mechanism
注記:If unused fields are not validated, shared business logic in an action may allow attackers to bypass the validation checks that are performed for other uses of the form. | |
潜在的な緩和策
Phases : Implementation
Validate all form fields. If a field is unused, it is still important to constrain it so that it is empty or undefined.
検出方法
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.)
脆弱性マッピングノート
理由 : 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.
コメント : 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.
