Input Validation","The product receives input or data, but it does\n        not validate or incorrectly validates that the input has the\n        properties that are required to process the data safely and\n        correctly.","Input validation is a frequently-used technique\n\t   for checking potentially dangerous inputs in order to\n\t   ensure that the inputs are safe for processing within the\n\t   code, or when communicating with other components.  When\n\t   software does not validate input properly, an attacker is\n\t   able to craft the input in a form that is not expected by\n\t   the rest of the application. This will lead to parts of the\n\t   system receiving unintended input, which may result in\n\t   altered control flow, arbitrary control of a resource, or\n\t   arbitrary code execution.\nInput validation is not the only technique for\n\t   processing input, however.  Other techniques attempt to\n\t   transform potentially-dangerous input into something safe, such\n\t   as filtering (CWE-790) - which attempts to remove dangerous\n\t   inputs - or encoding\u002Fescaping (CWE-116), which attempts to\n\t   ensure that the input is not misinterpreted when it is included\n\t   in output to another component. Other techniques exist as well\n\t   (see CWE-138 for more examples.)\nInput validation can be applied to:\nData can be simple or structured.  Structured data\n\t   can be composed of many nested layers, composed of\n\t   combinations of metadata and raw data, with other simple or\n\t   structured data.\nMany properties of raw data or metadata may need\n\t   to be validated upon entry into the code, such\n\t   as:\nImplied or derived properties of data must often\n\t   be calculated or inferred by the code itself.  Errors in\n\t   deriving properties may be considered a contributing factor\n\t   to improper input validation.\nNote that \"input validation\" has very different\n\t   meanings to different people, or within different\n\t   classification schemes.  Caution must be used when\n\t   referencing this CWE entry or mapping to it.  For example,\n\t   some weaknesses might involve inadvertently giving control\n\t   to an attacker over an input when they should not be able\n\t   to provide an input at all, but sometimes this is referred\n\t   to as input validation.\nFinally, it is important to emphasize that the\n\t   distinctions between input validation and output escaping\n\t   are often blurred, and developers must be careful to\n\t   understand the difference, including how input validation\n\t   is not always sufficient to prevent vulnerabilities,\n\t   especially when less stringent data types must be\n\t   supported, such as free-form text. Consider a SQL injection\n\t   scenario in which a person's last name is inserted into a\n\t   query. The name \"O'Reilly\" would likely pass the validation\n\t   step since it is a common last name in the English\n\t   language. However, this valid name cannot be directly\n\t   inserted into the database because it contains the \"'\"\n\t   apostrophe character, which would need to be escaped or\n\t   otherwise transformed. In this case, removing the\n\t   apostrophe might reduce the risk of SQL injection, but it\n\t   would produce incorrect behavior because the wrong name\n\t   would be recorded.","Stable","Class","Simple",{"id":119,"name":120,"description":121,"extendedDescription":122,"status":123,"abstraction":124,"structure":117},"CWE-444","Inconsistent Interpretation of HTTP Requests ('HTTP Request\u002FResponse Smuggling')","The product acts as an intermediary HTTP agent\n         (such as a proxy or firewall) in the data flow between two\n         entities such as a client and server, but it does not\n         interpret malformed HTTP requests or responses in ways that\n         are consistent with how the messages will be processed by\n         those entities that are at the ultimate destination.","HTTP requests or responses (\"messages\") can be\n\t   malformed or unexpected in ways that cause web servers or\n\t   clients to interpret the messages in different ways than\n\t   intermediary HTTP agents such as load balancers, reverse\n\t   proxies, web caching proxies, application firewalls,\n\t   etc. For example, an adversary may be able to add duplicate\n\t   or different header fields that a client or server might\n\t   interpret as one set of messages, whereas the intermediary\n\t   might interpret the same sequence of bytes as a different\n\t   set of messages. For example, discrepancies can arise in\n\t   how to handle duplicate headers like two Transfer-encoding\n\t   (TE) or two Content-length (CL), or the malicious HTTP\n\t   message will have different headers for TE and\n\t   CL.\nThe inconsistent parsing and interpretation of messages\n\t   can allow the adversary to \"smuggle\" a message to the\n\t   client\u002Fserver without the intermediary being aware of it.\nThis weakness is usually the result of the usage\n\t   of outdated or incompatible HTTP protocol versions in the\n\t   HTTP agents.","Incomplete","Base",2,false,[],{"title":129,"metaDescription":130,"keywords":131,"canonicalUrl":132,"structuredData":133},"What is CVE-2020-25097?
