shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -d /path/to/test -e txt
6. -r or –request
– Description: Specifies the type of HTTP request method to be used. Common methods include GET, POST, and HEAD.
– Example:
shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -r GET
7. -o or –output
– Description: Defines the output file where the results of the fuzzing process will be saved.
– Example:
shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -o results.txt
8. -v or –verbose
– Description: Enables verbose mode, providing detailed information about the fuzzing process. This can be helpful for troubleshooting and understanding the tool's behavior.
– Example:
shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -v
9. -t or –timeout
– Description: Sets the timeout value for each request. This is useful for controlling the duration of the fuzzing process, especially when dealing with slow or unresponsive servers.
– Example:
shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -t 10
10. -u or –user
– Description: Specifies the username for authentication, if required by the target service.
– Example:
shell
perl dotdotpwn.pl -m ftp -h 192.168.1.1 -p 21 -u username
11. -P or –password
– Description: Specifies the password for authentication, if required by the target service.
– Example:
shell
perl dotdotpwn.pl -m ftp -h 192.168.1.1 -p 21 -u username -P password
12. -c or –cookie
– Description: Defines the cookie string to be used in HTTP requests. This is particularly useful for testing web applications that require session management.
– Example:
shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -c "sessionid=abc123"
13. -a or –agent
– Description: Specifies the User-Agent string to be used in HTTP requests. This can help in bypassing certain security mechanisms that rely on User-Agent filtering.
– Example:
shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -a "Mozilla/5.0"
14. -H or –header
– Description: Allows the inclusion of additional HTTP headers in the requests. This can be used to customize the request further and simulate different client behaviors.
– Example:
shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -H "X-Custom-Header: value"
15. -f or –file
– Description: Specifies a file containing a list of payloads to be used during the fuzzing process. This allows for more extensive and customized testing.
– Example:
shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -f payloads.txt
16. -b or –base
– Description: Defines the base directory to be used in the payloads. This can help in targeting specific directory structures within the application.
– Example:
shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -b /base/dir
17. -i or –interval
– Description: Sets the interval between each request. This can be useful for avoiding detection by rate-limiting mechanisms or for reducing the load on the target server.
– Example:
shell
perl dotdotpwn.pl -m http -h 192.168.1.1 -p 80 -i 1
18. -l or –log
– Description: Specifies the log file where detailed information about the fuzzing process will be recorded. This can be useful for later analysis and reporting.
– Example:
{{EJS39}}Practical Examples
Example 1: Basic HTTP Fuzzing
To perform a basic directory traversal fuzzing on an HTTP web application running on `example.com` at port `80`, you would use the following command:
{{EJS40}}Example 2: FTP Fuzzing with Authentication
To fuzz an FTP server at `192.168.1.1` on port `21` using the username `ftpuser` and password `ftppass`, the command would be:
{{EJS41}}Example 3: HTTP Fuzzing with Custom Headers and Cookies
For a more complex scenario where you need to include a custom header and a session cookie in your HTTP requests, the command would look like this:
{{EJS42}}Example 4: Generating Payloads Only
If you want to generate payloads without actually sending them to a target, you can use the `payload` mode. This is useful for creating custom payloads for manual testing or integration into other tools:
shell
perl dotdotpwn.pl -m payload -o payloads.txt
