Weaknesses
CWE · root cause- CWE-77Improper Neutralization of Special Elements used in a Command ('Command Injection')The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
- CWE-351Insufficient Type DistinctionThe product does not properly distinguish between different types of elements in a way that leads to insecure behavior.
- CWE-451User Interface (UI) Misrepresentation of Critical InformationThe user interface (UI) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. This is often a component in phishing attacks.
