ACTION RECOMMENDED – Windows Vulnerability

The following legacy OS versions (Windows 7 / XP / XP Pro / XP Embedded and Windows Server 2008 / 2003) are susceptible to CVE-2019-0708, a critical Remote Code Execution vulnerability.

Given the potential impact to customers and their businesses, Microsoft has made the security updates available for platforms that are no longer offered mainstream support.

Despite the patches being made available by Microsoft, GBS recommends moving away from any operating system that is not fully supported by the manufacturer. If your organization is running any of these legacy operating systems – contact us to discuss an upgrade plan.




A flaw in many Cisco routers puts work email and so much more at high risk.

The vulnerability is due to an improper check on the area of code that manages on-premise updates to a Field Programmable Gate Array (FPGA) part of the Secure Boot hardware implementation.

It is vulnerable to remote tampering. And it gets worse because the data is stored unencrypted in flash that is accessible to the main processor. This allows an update to the firmware. Since the firmware can be modified, the device may need to be replaced to resolve the compromise.

Bad actors can load code using this method and compromise the router completely. Allowing internal communications that aren’t always encrypted with strong encryption to be read by the bad actors.
