The Boa web server - what is it?

The Boa Web Server was discontinued in 2005, but was a popular web server embedded in IoT devices to access configuration settings.

Why should we be concerned?

Microsoft recently did a survey (Vulnerable SDK components lead to supply chain risks in IoT and OT environments) and found over 1 million Boa web servers exposed on the internet. This is even more concerning given Boa has vulnerabilities that won’t be patched, including:

CVE-2022-45956 - Attackers can bypass authentication
CVE-2018-21028 - Attackers can trigger a memory leak

The CVE Program is maintained by the MITRE corporation and sponsored by the U.S. Department of Homeland Security (DHS) and the Cybersecurity and Infrastructure Security Agency (CISA). The CVE List is a list of publicly disclosed cyber security vulnerabilities and exposures that is free to search, use, and incorporate into products and services. - Mitre

TechCrunch highlighted in a November 2022 article that supply chains are at risk because of IoT Devices running Boa Web Server, which could leave Critical National Infrastructure open to attacks.

FractalScan Surface is trusted by companies worldwide

What our customers say

"FractalScan Surface is an impressive tool that we use to monitor our external cyber risks and those of our dealers worldwide. We've even used it to perform due diligence security checks on third-party suppliers.

I appreciate the easy-to-understand summary views, and my team likes that the daily scans automatically reflect their ongoing risk mitigation efforts.

I'd really encourage other companies to use this tool and start tracking their cyber risks."

Ken Shannon

IT Security Manager, Haas Automation Inc.
"As one of the first beta testers for FractalScan Surface, we've seen the product maturing into a comprehensive tool for monitoring our attack surface. We were then very happy to sign-up to the Premium Tier of FractalScan, adding to our security tool suite. I find FractalScan's user interface easy to use, allowing us to efficiently identify new risks and changes in our attack surface.

FractalScan's capability to mark domains hosted on shared cloud services gives us the ability to remove risks associated with IP addresses which are not part of our infrastructure, allowing us to focus our resources. The consultancy we've had from the professional services team at Red Maple Technologies confirms the credibility and background of the team building FractalScan. I'm excited to see what's coming next for FractalScan."

Robin Craib

Staff Information Security, VTS.
"FractalScan Surface has been great for discovering our online-visible assets and exposures, allowing us to make some immediate improvements to reduce our cyber risk."

Daily scanning enables us to keep on top of our external attack surface, which is particularly important to us since we have complex digital content output.

FractalScan gives us the view on our data we didn't have."
