Techniques & Countermeasures

  • CWE-94•Improper Control of Generation of Code ('Code Injection')

    The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
