No Rate-limit on Verify-email

---

Steps To Reproduce :

• 1 - Navigate to : https://abc.target.com/verify-email

• 2 - Intercept the request in BurpSuite

• 3 - Send the request to Intruder and clear the payload position

• 4 - Use Null payloads as payload type and set the payload count to 100

• 5 - Start attack

---

Impact :

• If the company is using any email service software API or some tool that has been bought for the emails being sent on the support domain, the rate limit can result in financial loss and it can also slow down your services as huge/mass mails will lead to disruption of data that original user might send or the quota that has been bought might be exhausted.

Mitigation :

• 1 - IP Based Blocking

• 2 - Captcha

• 3 - Firewall

• 4 - Reducing the number of API requests
