Module Overview

Name: Agent Tesla Panel Remote Code Execution
Module: exploit/multi/http/agent_tesla_panel_rce
Source code: modules/exploits/multi/http/agent_tesla_panel_rce.rb
Disclosure date: 2019-08-14
Last modification time: 2021-02-24 20:24:57 +0000
Supported architecture(s): php
Supported platform(s): PHP
Target service / protocol: http, https

List of CVEs: -

This module exploits a command injection vulnerability within the Agent Tesla control panel, in combination with an SQL injection vulnerability and a PHP object injection vulnerability, to gain remote code execution on affected hosts. Panel versions released prior to Sepetember 12, 2018 can be exploited by unauthenticated attackers to gain remote code execution as user running the web server. Agent Tesla panels released on or after this date can still be exploited however, provided that attackers have valid credentials for the Agent Tesla control panel. Note that this module presently only fully supports Windows hosts running Agent Tesla on the WAMP stack. Support for Linux may be added in a future update, but could not be confirmed during testing.

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.

Reliability:

• repeatable-session: The module is expected to get a shell every time it runs.

Stability:

• crash-safe: Module should not crash the service.

Side Effects:

• ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
• artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.

Basic Usage

Using agent_tesla_panel_rce against a single host

Normally, you can use exploit/multi/http/agent_tesla_panel_rce this way:

msf > use exploit/multi/http/agent_tesla_panel_rce
msf exploit(agent_tesla_panel_rce) > show targets
    ... a list of targets ...
msf exploit(agent_tesla_panel_rce) > set TARGET target-id
msf exploit(agent_tesla_panel_rce) > show options
    ... show and set options ...
msf exploit(agent_tesla_panel_rce) > exploit

Using agent_tesla_panel_rce 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 agent_tesla_panel_rce 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/multi/http/agent_tesla_panel_rce")
  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

Payload information:

Description:
  This module exploits a command injection vulnerability within the 
  Agent Tesla control panel, in combination with an SQL injection 
  vulnerability and a PHP object injection vulnerability, to gain 
  remote code execution on affected hosts. Panel versions released 
  prior to Sepetember 12, 2018 can be exploited by unauthenticated 
  attackers to gain remote code execution as user running the web 
  server. Agent Tesla panels released on or after this date can still 
  be exploited however, provided that attackers have valid credentials 
  for the Agent Tesla control panel. Note that this module presently 
  only fully supports Windows hosts running Agent Tesla on the WAMP 
  stack. Support for Linux may be added in a future update, but could 
  not be confirmed during testing.
