# Moxa MiiNePort Vulnerabilities
#


### OVERVIEW

Independent researcher Karn Ganeshen has identified weak credential management, sensitive information not protected, and cross-site request forgery vulnerabilities in Moxa's MiiNePort serial device server module series. Moxa will produce a beta patch firmware in late May 2016 to mitigate these vulnerabilities.

These vulnerabilities could be exploited remotely.




# AFFECTED PRODUCTS

The following MiiNePort versions are affected:

MiiNePort_E1_7080 Firmware Version 1.1.10 Build 09120714,
MiiNePort_E1_4641 Firmware Version 1.1.10 Build 09120714,
MiiNePort_E2_1242 Firmware Version 1.1 Build 10080614,
MiiNePort_E2_4561 Firmware Version 1.1 Build 10080614, and
MiiNePort E3 Firmware Version 1.0 Build 11071409.






### IMPACT

Successful exploitation of these vulnerabilities allow silent execution of unauthorized actions on the device such as password change, configuration parameter changes, saving modified configuration, and device reboot.

Impact to individual organizations depends on many factors that are unique to each organization.






### BACKGROUND

Moxa is a Taiwan-based company that maintains offices in several countries around the world, including the US, the UK, India, Germany, France, China, Russia, and Brazil.

The affected product, MiiNePort, is a serial device server module. According to Moxa, MiiNePort is deployed across several sectors including Commercial Facilities, Critical Manufacturing, Energy, and Transportation Systems. Moxa estimates that this product is used primarily in the United States and Europe with a small percentage in Asia.





### VULNERABILITY CHARACTERIZATION


# VULNERABILITY OVERVIEW

CLEARTEXT STORAGE OF SENSITIVE INFORMATION

Information strings are shown in clear text when viewing device config file.
CVE-2016-2295 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).



CROSS-SITE REQUEST FORGERY

The web application does not sufficiently verify whether a well-formed, consistent request was intentionally provided by the user who submitted the request.
CVE-2016-2285 has been assigned to this vulnerability. A CVSS v3 base score of 6.1 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).




WEAK CREDENTIAL MANAGEMENT

By default, no password is set on the device.
CVE-2016-2286 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).






### VULNERABILITY DETAILS


# EXPLOITABILITY

These vulnerabilities could be exploited remotely.


# EXISTENCE OF EXPLOIT

No known public exploits specifically target these vulnerabilities.


# DIFFICULTY

An attacker with a low skill would be able to exploit these vulnerabilities.





### MITIGATION

Moxa recommends disabling Ports TCP/80 (HTTP) and TCP/23 (TELNET). Moxa indicates that users should ensure that Ports UDP/161 (SNMP), UDP/4800 (utility), and TCP/4900 (utility) are only accessible by trusted systems and that restricting access to Ports UDP/4800 and TCP/4900 will impact remote systems administration.

Ensure the passwords have been enabled.
