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:

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.
