List of CVEs: CVE-2020-11698
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.
Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. 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:
- config-changes: Module modifies some configuration setting on the target machine.
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
Basic Usage
msf > use exploit/freebsd/webapp/spamtitan_unauth_rce
msf exploit(spamtitan_unauth_rce) > exploit
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
Knowledge Base
Vulnerable Application
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.
Installation
A demo version of the vulnerable application can be downloaded here. Since the latest version of SpamTitan Gateway has this vulnerability fixed and no demo of the vulnerable versions are available for download, the previous major release demo has to be used and updates have to be installed manually.
Installation steps:
1. Download SpamTitan Gateway version 6 demo .ova image:
https://stdownload.titanhq.com/vmware/SpamTitan-6-amd64.ova
2. Import it to your favorite virtualization software and start it
3. Access the SpamTitan web user interface from the appliance IP. This IP is
usually displayed on the welcome page once the virtual machine has boot up.
4. Login with the default credentials:
- username: admin
- password: hiadmin
5. Go to System Setup > System Updates and click Start in the Check for
Updates Now section. It will download all available update patches.
6. From the Available Updates section, choose the version you want to test
and click the install button in front of it.
Verification Steps
- Install the application (see Installation)
- Start msfconsole
- Do:
use exploit/freebsd/webapp/spamtitan_unauth_rce - Do:
set RHOSTS <ip> - Do:
set LHOST <ip> - Do:
run - You should get a shell.
Options
TARGETURI
The base path to SpamTitan. Default value is /.
USERNAME
The username to authenticate, if required (depending on SpamTitan Gateway
version). Default value is admin.
PASSWORD
The password to authenticate, if required (depending on SpamTitan Gateway
version). Default value is hiadmin.
COMMUNITY
The SNMP Community String to use (random string by default).
ALLOWEDIP
The IP address that will be allowed to query the injected extend command.
This IP will be added to the SNMP configuration file on the target. This is
tipically this host IP address, but can be different if your are in a NAT'ed
network. If not set, LHOST will be used instead. If LHOST is not set, it
will default to 127.0.0.1.
SNMPPORT
The target SNMP port (UDP). Default port is 161.

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.
