CVE-2023-43870 — When installing the Net2 software a root certificate is installed into the trusted store

Critical CVSS 9.8

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.

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
