Techniques & Countermeasures

  • CWE-917•Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection')

    The product constructs all or part of an expression language (EL) statement in a framework such as a Java Server Page (JSP) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended EL statement before it is executed.

  • CWE-20•Improper Input Validation

    The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
