일반적인 결과

범위	영향	가능성
Access Control	Bypass Protection Mechanism 참고: Binding to the address 0.0.0.0 might be much broader access than intended by the developer or administrator, who might only be expecting the server to be reachable from a single interface/network.
Availability	DoS: Amplification	High

잠재적 완화 방법

Phases : System Configuration
Assign IP addresses that are not 0.0.0.0.
Phases : System Configuration
Unwanted connections to the configured server may be denied through a firewall or other packet filtering measures.

취약점 매핑 메모

근거 : 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.
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.

관련 공격 패턴

CAPEC ID	공격 패턴 이름
CAPEC-1	Accessing Functionality Not Properly Constrained by ACLs In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
