Description

TitanHQ SpamTitan Gateway is an anti-spam appliance that protects against
unwanted emails and malwares. This module exploits an improper input
sanitization in versions 7.01, 7.02, 7.03 and 7.07 to inject command directives
into the SNMP configuration file and get remote code execution as root. Note
that only version 7.03 needs authentication and no authentication is required
for versions 7.01, 7.02 and 7.07.

First, it sends an HTTP POST request to the `snmp-x.php` page with an `SNMPD`
command directives (`extend` + command) passed to the `community` parameter.
This payload is then added to `snmpd.conf` by the application. Finally, the
module triggers the execution of this command by querying the SNMP server for
the correct OID.

This exploit module has been successfully tested against versions 7.01, 7.02,
7.03, and 7.07.
