Without sufficient protection mechanisms, the functionality could be malicious in nature (either by coming from an untrusted source, being spoofed, or being modified in transit from a trusted source). The functionality might also contain its own weaknesses, or grant access to additional functionality and state information that should be kept private to the base system, such as system state information, sensitive application data, or the DOM of a web application.\nThis might lead to many different consequences depending on the included functionality, but some examples include injection of malware, information exposure by granting excessive privileges or permissions to the untrusted functionality, DOM-based XSS vulnerabilities, stealing user's cookies, or open redirect to malware (CWE-601).","Incomplete","Base","Simple",{"id":66,"name":67,"description":68,"extendedDescription":69,"status":62,"abstraction":70,"structure":64},"CWE-830","Inclusion of Web Functionality from an Untrusted Source","The product includes web functionality (such as a web widget) from another domain, which causes it to operate within the domain of the product, potentially granting total access and control of the product to the untrusted source.","Including third party functionality in a web-based environment is risky, especially if the source of the functionality is untrusted.\nEven if the third party is a trusted source, the product may still be exposed to attacks and malicious behavior if that trusted source is compromised, or if the code is modified in transmission from the third party to the product.\nThis weakness is common in \"mashup\" development on the web, which may include source functionality from other domains. For example, Javascript-based web widgets may be inserted by using '\u003CSCRIPT SRC=\"http:\u002F\u002Fother.domain.here\">' tags, which causes the code to run in the domain of the product, not the remote site from which the widget was loaded. As a result, the included code has access to the local DOM, including cookies and other data that the developer might not want the remote site to be able to access.\nSuch dependencies may be desirable, or even required, but sometimes programmers are not aware that a dependency exists.","Variant",2,false,[],{"title":75,"metaDescription":76,"keywords":77,"canonicalUrl":78,"structuredData":79},"What is CVE-2021-28162?
