about what constitutes data and control respectively. It is the lack of verification of these assumptions for user-controlled input that leads to injection problems. Injection problems encompass a wide variety of issues -- all mitigated in very different ways and usually attempted in order to alter the control flow of the process. For this reason, the most effective way to discuss these weaknesses is to note the distinct features that classify them as injection weaknesses. The most important issue to note is that all injection problems share one thing in common -- i.e., they allow for the injection of control plane data into the user-controlled data plane. This means that the execution of the process may be altered by sending code in through legitimate data channels, using no other mechanism. While buffer overflows, and many other flaws, involve the use of some further issue to gain execution, injection problems need only for the data to be parsed.","Incomplete","Class","Simple",{"id":99,"name":100,"description":101,"extendedDescription":102,"status":95,"abstraction":103,"structure":97},"CWE-792","Incomplete Filtering of One or More Instances of Special Elements","The product receives data from an upstream component, but does not completely filter one or more instances of special elements before sending it to a downstream component.","Incomplete filtering of this nature involves either:","Variant",2,false,[],{"title":108,"metaDescription":109,"keywords":110,"canonicalUrl":111,"structuredData":112},"What is CVE-2023-20057?
