CWE-1327: Binding to an Unrestricted IP Address
Presentation Filter:
The product assigns the address 0.0.0.0 for a database server, a cloud service/instance, or any computing resource that communicates remotely. When a server binds to the address 0.0.0.0, it allows connections from every IP address on the local machine, effectively exposing the server to every possible network. This 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. The table(s) below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore. ![]()
The different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase.
The listings below show possible areas for which the given weakness could appear. These may be for specific named Languages, Operating Systems, Architectures, Paradigms, Technologies, or a class of such platforms. The platform is listed along with how frequently the given weakness appears for that instance. Languages Other (Undetermined Prevalence) Operating Systems Class: OS-Independent (Undetermined Prevalence) Architectures Class: Architecture-Independent (Undetermined Prevalence) Technologies Web Server (Undetermined Prevalence) Class: Client Server (Undetermined Prevalence) Class: Cloud Computing (Undetermined Prevalence) The table below specifies different individual consequences associated with the weakness. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.
Example 1 The following code snippet uses 0.0.0.0 in a Puppet script. (bad code) Example Language: Other
signingserver::instance {
"nightly-key-signing-server":
listenaddr => "0.0.0.0",
}port => "9100", code_tag => "SIGNING_SERVER", The Puppet code snippet is used to provision a signing server that will use 0.0.0.0 to accept traffic. However, as 0.0.0.0 is unrestricted, malicious users may use this IP address to launch frequent requests and cause denial of service attacks. (good code) Example Language: Other
signingserver::instance {
"nightly-key-signing-server":
listenaddr => "127.0.0.1",
}port => "9100", code_tag => "SIGNING_SERVER",
