# Moxa SoftCMS Vulnerabilities
#


### OVERVIEW

Zhou Yu working with Trend Micro's Zero Day Initiative and Gu Ziqiang from Huawei Weiran Labs have identified vulnerabilities in Moxa's SoftCMS Webserver Application. Moxa has produced an update to mitigate these vulnerabilities. Both researchers have tested the update to validate that it resolves these vulnerabilities.
These vulnerabilities could be exploited remotely.



### AFFECTED PRODUCTS

Moxa reports that the vulnerabilities affect the following versions of SoftCMS:
SoftCMS versions prior to Version 1.6



### IMPACT

A successful exploit could allow an attacker to execute arbitrary commands on the target system, as well as gain access to administrative functions of the application.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation.



### BACKGROUND

Moxa is a Taiwan-based company that maintains offices in several countries around the world, including the US, UK, India, Germany, France, China, Russia, and Brazil.
The affected product, SoftCMS, is a central management software that manages large scale surveillance systems. According to Moxa, SoftCMS 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

IMPROPER INPUT VALIDATIONa
Moxa SoftCMS Webserver does not properly validate input. An attacker could provide unexpected values and cause the program to crash or excessive consumption of resources could result in a denial-of-service condition.
CVE-2016-9332b 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:N/I:N/A:H)

DOUBLE FREEd
A specially crafted URL request sent to the SoftCMS ASP Webserver can cause a double free condition on the server allowing an attacker to modify memory locations and possibly cause a denial of service or the execution of arbitrary code.
CVE-2016-8360e has been assigned to this vulnerability. A CVSS v3 base score of 8.1 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

SQL INJECTIONg
The SoftCMS Application does not properly sanitize input that may allow a remote attacker access to SoftCMS with administrator's privilege through specially crafted input.
CVE-2016-9333h has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)




### 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's suggested mitigation is to update the application (SoftCMS v1.6), which is available for download from Moxa's web site at the following link:
