"The software uses a cookie to store sensitive information, but the cookie is not marked with the HttpOnly flag.",
"The software displays information or identifiers to a user, but the display mechanism does not make it easy for the user to distinguish between visually similar or identical glyphs (homoglyphs), which may cause the user to misinterpret a glyph and perform an unintended, insecure action.",
"The application uses multiple validation forms with the same name, which might cause the Struts Validator to validate a form that the programmer does not expect.",
"The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain, which can lead to user confusion about which interface the user is interacting with.",
"The web application produces links to untrusted external sites outside of its sphere of control, but it does not properly prevent the external site from modifying security-critical properties of the window.opener object, such as the location property.",
"The software performs a comparison between entities that must consider multiple factors or characteristics of each entity, but the comparison does not include one or more of these factors.",
"The software performs a comparison between two entities, but the entities are of different, incompatible types that cannot be guaranteed to provide correct results when they are directly compared.",
"The code performs a comparison between two entities, but the comparison examines the wrong factors or characteristics of the entities, which can lead to incorrect results and resultant weaknesses.",
"The application has a validator form that either does not define a validate() method, or defines a validate() method but does not call super.validate().",
"The developer builds a security-critical protection mechanism into the software, but the processor optimizes the execution of the program such that the mechanism is removed or modified.",
"The product uses a mechanism that automatically optimizes code, e.g. to improve a characteristic such as performance, but the optimizations can have an unintended side effect that might violate an intended security assumption.",
"The product uses an automated mechanism such as machine learning to recognize complex data inputs (e.g. image or audio) as a particular concept or category, but it does not properly detect or handle inputs that have been modified or constructed in a way that causes the mechanism to detect a different, incorrect concept.",
"If a form bean does not extend an ActionForm subclass of the Validator framework, it can expose the application to other weaknesses related to insufficient input validation.",
"The software has multiple functions, methods, procedures, macros, etc. that\n\t\t\t\t\tcontain the same code.",
"The code contains a member element that is declared as static (but not final), in which\n\t\t\t\t\tits parent class element \n\t\t\t\t\tis not a singleton class - that is, a class element that can be used only once in\n\t\t\t\t\tthe 'to' association of a Create action.",

"The software performs a data query with a large number of joins\n\t\t\t\t\tand sub-queries on a large data table.",
"The application has a form field that is not validated by a corresponding validation form, which can introduce other weaknesses related to insufficient input validation.",
"The software has a loop body or loop condition that contains a control element that directly or\n\t\t\t\t\tindirectly consumes platform resources, e.g. messaging, sessions, locks, or file\n\t\t\t\t\tdescriptors.",
"The software initializes data using hard-coded values that act as network resource identifiers.",
"The software initializes a data element using a hard-coded\n\t\t\t\t\tliteral that is not a simple integer or static constant element.",
"The product does not have documentation that represents how it is designed.",
"The code at one architectural layer invokes code that resides\n\t\t\t\t\tat a deeper layer than the adjacent layer, i.e., the invocation skips at least one\n\t\t\t\t\tlayer, and the invoked code is not part of a vertical utility layer that can be referenced from any horizontal layer.",
"The software contains a class with inheritance from more than\n\t\t\t\t\tone concrete class.",
"A named-callable or method control element has a signature that\n\t\t\t\t\tsupports a variable (variadic) number of parameters or arguments.",
"The software uses a dedicated, central data manager component as required by design, but it contains code that performs data-access operations that do not use this data manager.",
"The code contains a function or method that\n\t\t operates in a multi-threaded environment but owns an unsafe non-final\n\t\t static storable or member data element.",
"The documentation, whether on paper or in electronic form, does\n\t\t\t\t\tnot contain descriptions of all the relevant elements of the product, such as\n\t\t\t\t\tits usage, structure, interfaces, design, implementation, configuration,\n\t\t\t\t\toperation, etc.",
"When an application does not use an input validation framework such as the Struts Validator, there is a greater risk of introducing weaknesses related to insufficient input validation.",
"The software performs too many data queries without using efficient data processing functionality such as stored procedures.",
"The software does not sufficiently hide the internal representation and implementation details of data or methods, which might allow external components or modules to modify data unexpectedly, invoke unexpected functionality, or introduce dependencies that the programmer did not intend.",
"The code has a parent class that contains references to a child class, its methods, or its members.",
"A static code block creates an instance of a class.",
"The software contains a function, subroutine, or method whose signature has an unnecessarily large number of\n\t\t\t\t\tparameters/arguments.",
"The application uses deployed components from application servers, but it also uses low-level functions/methods for management of resources, instead of the API provided by the application server.",
"The software contains a serializable data element that does not\n\t\t\t\t\thave an associated serialization method.",
"The software contains a data query against an SQL table or view\n\t\t\t\t\tthat is configured in a way that does not utilize an index and may cause\n\t\t\t\t\tsequential searches to be performed.",
"The implementation of the product is not consistent with the\n\t\t\t\t\tdesign as described within the relevant documentation.",
"An invokable code block contains an exception handling block that does not contain any code, i.e. is empty.",
"An unused validation form indicates that validation logic is not up-to-date.",

"The source code contains a block that does not contain any code, i.e., the block is empty.",
"The software accesses a data resource through a database without using a\n\t\t\t\t\tconnection pooling capability.",
"The software contains a client with a function or method that contains a large number of data accesses/queries that are sent through a data manager, i.e., does not use efficient database capabilities.",
"A class has an inheritance level that is too high, i.e., it\n\t\t\t\t\thas a large number of parent classes.",
"The software performs unconditional control transfer (such as a\n\t\t\t\t\t\"goto\") in code outside of a branching structure such as a switch\n\t\t\t\t\tblock.",
"The product's architecture, source code, design, documentation,\n\t\t\t\t\tor other artifact does not follow required conventions.",
"The code performs a comparison such as an\n equality test between two float (floating point) values, but\n it uses comparison operators that do not account for the\n possibility of loss of precision.",
"The source code does not follow\n\t\t\t\tdesired style or formatting for indentation, white\n\t\t\t\tspace, comments, etc.",
"A parent class contains one or more child classes, but the parent class does not have a virtual destructor method.",
"Every Action Form must have a corresponding validation form.",
"A source code file has too many lines of\n\t\t\t\t\tcode.",
"The code contains a class instance that calls the method or function to delete or destroy itself.",
"The software is intended to manage data access through a particular data manager component such as a relational or non-SQL database, but it contains code that performs data access operations without using that component.",
"A function or method contains too many\n\t\t\t\t\toperations that utilize a data manager or file resource.",

"The software uses a large data table that contains an excessively large number of\n\t\t\t\t\tindices.",
"Automatic filtering via a Struts bean has been turned off, which disables the Struts Validator and custom validation logic. This exposes the application to other weaknesses related to insufficient input validation.",
"A method for a class performs an operation that directly\n\t\t\t\t\taccesses a member element from another class.",
"The software contains a method that accesses an object but does not later invoke\n\t\t\t\t\tthe element's associated finalize/destructor method.",
