Redirect

Simple HTTP server that sends redirect responses. Useful when leveraging SSRF attacks.

Usage

Redirect customization

Specify host: At least you have to specify the host to redirect to with a positonal argument:

redirect http://127.0.0.1

This will redirect to 127.0.0.1 with the same path requested.

Specify schema: If no options are provided the redirect will default to HTTP. If you want to redirect to HTTPS, FTP, Gopher or anything else you can just add the schema to the host:

redirect ftp://127.0.0.1:2121

Specifically set a path: Maybe you just want to set a path. The -path flag sets a path to redirect:

redirect -path /custom/path  ftp://127.0.0.1:2121

Custom status code: By default redirect responses are served with status 301. Change it with the -status flag:

redirect -status 302 https://127.0.0.1:8443

Server configuration

Change listening address and port: By default the server listens at 0.0.0.0:8888, but you can change it with the -addr flag:

redirect -addr :8080 https://example.com

redirect -addr 127.0.0.1:8080 https://example.com

Dump the requests to stdout: The -dump flag lets you see what requests are reaching the server

redirect -dump ftp://127.0.0.1:25

Dump requests to a file: Just use the -dump flag with shell redirection > or the tee command:

redirect -dump http://127.0.0.1:25 > requests.log
redirect -dump http://127.0.0.1:25 | tee requests.log
