Perle Meltdown and Spectre Vulnerability Disclosure
The majority of Perle products are closed systems that do not allow customers to run custom code on the device, and thus are not vulnerable.
By: Perle Systems
The Meltdown vulnerability allows an attacker to bypass the hardware barriers between memory and applications running on the computer, which can allow an attacker to access data, passwords and crypto-keys.
The Spectre vulnerability breaks the isolation between applications that otherwise would be deemed error-free programs. This induces a program to leak its secrets and data using other processes within the memory to access the application.
To exploit any of these vulnerabilities, an attacker must be able to run crafted code on an affected device. Although the underlying CPU and operating system combination in a product may be affected by these vulnerabilities, the majority of Perle products are closed systems that do not allow customers to run custom code on the device, and thus are not vulnerable. There is no vector to exploit them.
Perle IOLAN Serial Terminal Servers are, by default, closed systems. However, they are considered potentially vulnerable if a user has written and installed their own custom code, using the Perle Software Development Kit (https://www.perle.com/
Perle recommends customers review Device Plug-ins that they have written and installed, using the Perle SDK, for vulnerabilities. If you are using a Device Plug-in supplied by Perle the system is closed and therefore not vulnerable.
