CWE-1293: Missing Source Correlation of Multiple Independent Data
View customized information:For users who are interested in more notional aspects of a weakness. Example: educators, technical writers, and project/program managers. For users who are concerned with the practical application and details about the nature of a weakness and how to prevent it from happening. Example: tool developers, security researchers, pen-testers, incident response analysts. For users who are mapping an issue to CWE/CAPEC IDs, i.e., finding the most appropriate CWE for a specific issue (e.g., a CVE record). Example: tool developers, security researchers. For users who wish to see all available information for the CWE/CAPEC entry. For users who want to customize what details are displayed.
The product relies on one source of data, preventing the ability to detect if an adversary has compromised a data source.
To operate successfully, a product sometimes has to implicitly trust the integrity of an information source. When information is implicitly signed, one can ensure that the data was not tampered in transit. This does not ensure that the information source was not compromised when responding to a request. By requesting information from multiple sources, one can check if all of the data is the same. If they are not, the system should report the information sources that respond with a different or minority value as potentially compromised. If there are not enough answers to provide a majority or plurality of responses, the system should report all of the sources as potentially compromised. As the seriousness of the impact of incorrect integrity increases, so should the number of independent information sources that would need to be queried.
This table 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.
Relevant to the view "Research Concepts" (CWE-1000)
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.
This listing shows 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.
Class: Not Language-Specific (Undetermined Prevalence)
Class: Not OS-Specific (Undetermined Prevalence)
Class: Not Architecture-Specific (Undetermined Prevalence)
Class: Not Technology-Specific (Undetermined Prevalence)
This table 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.
This MemberOf Relationships table shows additional CWE Categories and Views that reference this weakness as a member. This information is often useful in understanding where a weakness fits within the context of external information sources.
