How to fix CWE 829 - Inclusion of Functionality from Untrusted Control Sphere

Question

As part of veracode scan i got CWE 829 -Inclusion of Functionality from Untrusted Control Sphere error thrown.

Below I have pasted my Java code and in line#3 i'm getting this vulnerability.

I didn't find much about this issue. Can some one assist me if you have faced this kind of issue earlier?

import java.applet.Applet;
import java.awt.Graphics;

public class ShowVariables extends Applet { //Error shown in thos line
    int age = 35;
    double salary = 25000.34;
    long distance_to_the_moon = 235678;

    public void paint(Graphics g) {
        g.drawString("employees age: " + age, 5, 25);
        g.drawString("Employess salary: " + salary, 5, 45);
        g.drawString("Distance to the moon: " + distance_to_the_moon, 5, 65);

    }

}
