Nmap http-ls NSE Script


This page contains detailed information about how to use the http-ls NSE script. For list of all NSE scripts, visit the Nmap NSE Library.

Script Description

The http-ls.nse script shows the content of an "index" Web page.

TODO:

  • add support for more page formats

Http-ls NSE Script Arguments

This is a full list of arguments supported by the http-ls.nse script:

http-ls.checksum

Compute a checksum for each listed file. Requires OpenSSL. (default: false)

http-ls.url

Base URL path to use (default: /)

smbdomain

The domain to log in with. If you aren't in a domain environment, then anything will (should?) be accepted by the server.

smbhash

A password hash to use when logging in. This is given as a single hex string (32 characters) or a pair of hex strings (both 32 characters, optionally separated by a single character). These hashes are the LanMan or NTLM hash of the user's password, and are stored on disk or in memory. They can be retrieved from memory using the fgdump or pwdump tools.

smbnoguest

Use to disable usage of the 'guest' account.

smbpassword

The password to connect with. Be cautious with this, since some servers will lock accounts if the incorrect password is given. Although it's rare that the Administrator account can be locked out, in the off chance that it can, you could get yourself in trouble. To use a blank password, leave this parameter off altogether.

smbtype

The type of SMB authentication to use. These are the possible options:

  • v1: Sends LMv1 and NTLMv1.
  • LMv1: Sends LMv1 only.
  • NTLMv1: Sends NTLMv1 only (default).
  • v2: Sends LMv2 and NTLMv2.
  • LMv2: Sends LMv2 only.
  • NTLMv2: Doesn't exist; the protocol doesn't support NTLMv2 alone. The default, NTLMv1, is a pretty decent compromise between security and compatibility. If you are paranoid, you might want to use v2 or lmv2 for this. (Actually, if you're paranoid, you should be avoiding this protocol altogether!). If you're using an extremely old system, you might need to set this to v1 or lm, which are less secure but more compatible. For information, see smbauth.lua.

smbusername

The SMB username to log in with. The forms "DOMAIN\username" and "username@DOMAIN" are not understood. To set a domain, use the smbdomain argument.

slaxml.debug

Debug level at which default callbacks will print detailed parsing info. Default: 3

http.host

The value to use in the Host header of all requests unless otherwise set. By default, the Host header uses the output of stdnse.get_hostname().

http.max-body-size

Limit the received body to specific number of bytes. An oversized body results in an error unless script argument http.truncated-ok or request option truncated_ok is set to true. The default is 2097152 (2MB). Use value -1 to disable the limit altogether. This argument can be overridden case-by-case with request option max_body_size.

http.max-cache-size

The maximum memory size (in bytes) of the cache.

http.max-pipeline

If set, it represents the number of outstanding HTTP requests that should be sent together in a single burst. Defaults to http.pipeline (if set), or to what function get_pipeline_limit returns.

http.pipeline

If set, it represents the number of HTTP requests that'll be sent on one connection. This can be set low to make debugging easier, or it can be set high to test how a server reacts (its chosen max is ignored).

http.truncated-ok

Do not treat oversized body as error. (Use response object flag truncated to check if the returned body has been truncated.) This argument can be overridden case-by-case with request option truncated_ok.

http.useragent

The value of the User-Agent header field sent with requests. By default it is "Mozilla/5.0 (compatible; Nmap Scripting Engine; https://nmap.org/book/nse.html)". A value of the empty string disables sending the User-Agent header field.

ls.checksum

(boolean) Download each file and calculate a SHA1 checksum. Although this is a module argument, the implementation is done in each script and is currently only supported by smb-ls and http-ls

ls.empty

(boolean) Report empty volumes (with no information or error)

ls.errors

(boolean) Report errors

ls.human

(boolean) Show file sizes in human-readable format with K, M, G, T, P suffixes. Some services return human-readable sizes natively; in these cases, the size is reported as given.

ls.maxdepth

The maximum depth to recurse into a directory. If less than 0 (e.g. -1) then recursion is unlimited. (default: 0, no recursion).

ls.maxfiles

The maximum number of files to return. Set to 0 or less to disable this limit. (default: 10).

To use these script arguments, add them to the Nmap command line using the --script-args arg1=value,[arg2=value,..] syntax. For example:

nmap --script=http-ls --script-args http-ls.checksum=value,http-ls.url=value <target>

Http-ls NSE Script Example Usage

Here's an example of how to use the http-ls.nse script:

nmap -n -p 80 --script http-ls test-debit.free.fr
