Kingdom: Input Validation and Representation

Input validation and representation problems ares caused by metacharacters, alternate encodings and numeric representations. Security problems result from trusting input. The issues include: "Buffer Overflows," "Cross-Site Scripting" attacks, "SQL Injection," and many others.

Dynamic Code Evaluation: Code Manipulation

Abstract
Allowing unvalidated user-input to influence the run-time environment of dynamically executed code can allow attackers to execute malicious code.
Explanation
Many modern programming languages allow dynamic interpretation of source instructions. This capability allows programmers to execute dynamic operations based on input received from the user. Code manipulation vulnerabilities occur when the programmer allows some user supplied data to alter an aspect of run-time environment of dynamically executed code. Without proper validation, a user might specify operations the programmer does not intend.

Example 1: In this example, the application retrieves the script execution scope from the web application.


...
ScriptEngineManager scriptEngineManager = new ScriptEngineManager();
ScriptEngine scriptEngine = scriptEngineManager.getEngineByExtension("js");
ScriptContext newContext = new SimpleScriptContext();
Bindings engineScope = newContext.getBindings(request.getParameter("userName"));

userOps = request.getParameter("operation");
Object result = scriptEngine.eval(userOps,newContext);
...


The program behaves correctly when the page_scope parameter is the expected username. However, if an attacker specifies the value for GLOBAL_SCOPE, the operations will have access to all attributes within all engines created by the same ScriptEngine.
