OnCell G3100-HSPA Series Cellular Gateway/Router Vulnerabilities

Published: March 13, 2018

This Alert Is From MOXA

As Industrial IoT (IIoT) adoption continues to proliferate, cybersecurity has become one of the top priorities. The Moxa Product Security Incident Response Team (PSIRT) takes a proactive approach to protect products from cybersecurity vulnerabilities. Moxa PSIRT investigates all reports of vulnerabilities that could potentially affect Moxa products. Moxa created a vulnerability management policy to provide guidance and information to our customers in the event of a reported vulnerability. The management policy ensures that Moxa’s customers have steady, unambiguous resources to help them understand how Moxa resolves or mitigates reported vulnerabilities. For any queries, please email [email protected].

Multiple product vulnerabilities were identified in Moxa’s OnCell G3100-HSPA Series Cellular Gateway/Router. In response to this, Moxa has developed related solutions to address these vulnerabilities.

The identified vulnerability types and potential impacts are shown below:

Item Vulnerability Type Impact
1

Reliance on cookies without validation and integrity checking

 The application allows a cookie parameter to consist of only digits, allowing an attacker to perform a brute force attack bypassing authentication and gaining access to device functions.
2

Improper handling of length parameter inconsistency

 An attacker may be able to edit the element of an HTTP request, causing the device to become unavailable.
3

Null pointer dereference

 The application does not check for a NULL value, allowing for an attacker to perform a denial of service attack.
