CVE-2023-43870: Paxton-Access NET2

Critical severity, CVSS 9.8. EPSS: 0.4% chance of exploitation in the next 30 days.

When installing the Net2 software a root certificate is installed into the trusted store. A potential hacker could access the installer batch file or reverse engineer the source code to gain access to the root certificate password. Using the root certificate and password they could then create their own certificates to emulate another site. Then by establishing a proxy service to emulate the site they could monitor traffic passed between the end user and the site allowing access to the data content.

Affected products

• Paxton-Access NET2: from 6.02, before 6.07 (fixed in 6.07); version 6.07 only
