## Vulnerable Application
|
||||
|
||||
Pandora FMS (for Pandora Flexible Monitoring System) is software for
|
||||
monitoring computer networks. Pandora FMS allows monitoring in a visual
|
||||
way the status and performance of several parameters from different
|
||||
operating systems, servers, applications and hardware systems such
|
||||
as firewalls, proxies, databases, web servers or routers.
|
||||
|
||||
This module exploits a vulnerability found in Pandora FMS 7.0 NG and lower.
|
||||
The vulnerability exists on the `net_tools.php` component, due to the insecure
|
||||
usage of the `system()` PHP function.
|
||||
|
||||
This module has been tested with [Pandora FMS 7.0 NG](https://sourceforge.net/projects/pandora/files/Pandora%20FMS%207.0NG/Final/Pandora_FMS_7.0_NG_VmWare_ovf.zip/download)
|
||||
|
||||
## Verification Steps
|
||||
|
||||
Launch metasploit and set the appropriate options:
|
||||
|
||||
1. Start `msfconsole`
|
||||
2. `use exploit/linux/http/pandora_ping_cmd_exec`
|
||||
3. `set RHOSTS <rhosts>`
|
||||
4. `set LHOST <lhost>`
|
||||
5. `set USERNAME <username>`
|
||||
6. `set PASSWORD <password>`
|
||||
7. `exploit`
|
||||
|
||||
## Options
|
||||
|
||||
**USERNAME**
|
||||
|
||||
The username for Pandora FMS.
|
||||
|
||||
**PASSWORD**
|
||||
|
||||
The password for Pandora FMS.

||||

||||
