List of CVEs: CVE-2014-3704
Script Description
The http-vuln-cve2014-3704.nse script exploits CVE-2014-3704 also known as 'Drupageddon' in Drupal. Versions < 7.32 of Drupal core are known to be affected.
Vulnerability allows remote attackers to conduct SQL injection attacks via an array containing crafted keys.
The script injects new Drupal administrator user via login form and then it attempts to log in as this user to determine if target is vulnerable. If that's the case following exploitation steps are performed:
- PHP filter module which allows embedded PHP code/snippets to be evaluated is enabled,
- permission to use PHP code for administrator users is set,
- new article which contains payload is created & previewed,
- cleanup: by default all DB records that were added/modified by the script are restored.
Vulnerability originally discovered by Stefan Horst from SektionEins.
Exploitation technique used to achieve RCE on the target is based on exploit/multi/http/drupal_drupageddon Metasploit module.
Http-vuln-cve2014-3704 NSE Script Arguments
This is a full list of arguments supported by the http-vuln-cve2014-3704.nse script:
http-vuln-cve2014-3704.cleanupIndicates whether cleanup (removing DB records that was added/modified during exploitation phase) will be done. Default: true
http-vuln-cve2014-3704.cmdShell command to execute. Default: nil
http-vuln-cve2014-3704.uriDrupal root directory on the website. Default: /
smbdomainThe domain to log in with. If you aren't in a domain environment, then anything will (should?) be accepted by the server.
smbhashA 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.
smbnoguestUse to disable usage of the 'guest' account.
smbpasswordThe 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.
smbtypeThe 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 usev2
orlmv2
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 tov1
orlm
, which are less secure but more compatible. For information, seesmbauth.lua
.
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.
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()
.
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
.
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.
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
.
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.
If set, vulnerabilities will be output in short format, a single line consisting of the host's target name or IP, the state, and either the CVE ID or the title of the vulnerability. Does not affect XML output.
vulns.showall
If set, the library will show and report all the registered vulnerabilities which includes the NOT VULNERABLE
ones. By default the library will only report the VULNERABLE
entries: VULNERABLE
, LIKELY VULNERABLE
, VULNERABLE (DoS)
and VULNERABLE (Exploitable)
. This argument affects the following functions: vulns.Report.make_output(): the default output function for portule/hostrule scripts. vulns.make_output(): the default output function for postrule scripts. vulns.format_vuln() and vulns.format_vuln_table() functions.

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-vuln-cve2014-3704 --script-args http-vuln-cve2014-3704.cleanup=value,http-vuln-cve2014-3704.cmd=value <target>
