Published: December 1, 2021

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 ioPAC 8500 Series (IEC models) and ioPAC 8600 Series (IEC models) rugged modular programmable controllers. 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 Relative path traversal (CWE23) CVE-2020-25176 It is possible for an unauthenticated attacker located remotely to traverse an application’s directory, which could lead to remote code execution.
2 Cleartext transmission of sensitive information (CWE-319) CVE-2020-25178 Data is transferred over this protocol unencrypted, which could allow an attacker located remotely to upload, read, and delete files.
3 Use of hard-coded cryptographic key (CWE-321) CVE-2020-25180 An unauthenticated attacker located remotely could pass their own encrypted password to the ISaGRAF 5 Runtime, which may result in information disclosure on the device.
4 Unprotected storage of credentials (CWE-256) CVE-2020-25184 An unauthenticated attacker at the site could compromise user’s passwords, resulting in information disclosure.
