Script Description

The http-axis2-dir-traversal.nse script exploits a directory traversal vulnerability in Apache Axis2 version 1.4.1 by sending a specially crafted request to the parameter xsd (BID 40343). By default it will try to retrieve the configuration file of the Axis2 service '/conf/axis2.xml' using the path '/axis2/services/' to return the username and password of the admin account.

To exploit this vulnerability we need to detect a valid service running on the installation so we extract it from /listServices before exploiting the directory traversal vulnerability. By default it will retrieve the configuration file, if you wish to retrieve other files you need to set the argument http-axis2-dir-traversal.file correctly to traverse to the file's directory. Ex. ../../../../../../../../../etc/issue

Http-axis2-dir-traversal NSE Script Arguments

This is a full list of arguments supported by the http-axis2-dir-traversal.nse script:

http-axis2-dir-traversal.basepath

Basepath to the services page. Default: /axis2/services/

http-axis2-dir-traversal.file

Remote file to retrieve

http-axis2-dir-traversal.outfile

Output file

creds.global

Credentials to be returned by Credentials.getCredentials regardless of the service.

creds.[service]

Credentials to be returned by Credentials.getCredentials for [service]. E.g. creds.http=admin:password

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.

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-axis2-dir-traversal --script-args http-axis2-dir-traversal.basepath=value,http-axis2-dir-traversal.file=value <target>

Http-axis2-dir-traversal NSE Script Example Usage

Here's an example of how to use the http-axis2-dir-traversal.nse script:

nmap -p80,8080 --script http-axis2-dir-traversal --script-args 'http-axis2-dir-traversal.file=../../../../../../../etc/issue' <host/ip>

nmap -p80 --script http-axis2-dir-traversal <host/ip>

Http-axis2-dir-traversal NSE Script Example Output

Here's a sample output from the http-axis2-dir-traversal.nse script:

80/tcp open  http    syn-ack
|_http-axis2-dir-traversal.nse: Admin credentials found -> admin:axis2

Http-axis2-dir-traversal NSE Script Example XML Output

There is no sample XML output for this module. However, by providing the -oX <file> option, Nmap will produce a XML output and save it in the file.xml file.
