Description

The commafeedapplication allows large characters to insert in the input field "password" at password change feature which can allow attackers to cause a Denial of Service (DoS) via a crafted HTTP request.

Proof of Concept

1. Login and go to profile
2. Go to password change feature 
3. Fill your current password, fill the "Password" and "Password (agian)" input field with huge characters (more than 1 lakh)
4. Click "Change password"
You will see the application accepts large characters. If we increase the characters then it can lead to Dos.

Payload

You can get the large character at there (you can increase more) https://drive.google.com/file/d/1Q_optB_MfI7byzpS7SB8kPeVNc2DebwT/view?usp=sharing

Impact

This weakness will generally lead to undefined behavior and therefore crashes. Such as DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Instability
