Description

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

Proof of Concept

1. Register a new account or go to https://app.titra.io/join?email=
2. Fill a normal email, fill the "Password" and "Password (agian)" input field with huge characters (more than 1 lakh)
3. Register
You will see the application accepts large characters and if we will 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

Patch recemmondation:

The password input should be limited to 50 characters or less

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
