CVE-2023-43870
CWE-798Published: December 19, 2023· Updated: Jun 17, 2026
Official Description
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.
Risk Analysis
The Net2 software installer exposes a root certificate and password, which could allow an attacker to emulate sites and intercept traffic. This critical 9.8 CVSS vulnerability enables man-in-the-middle attacks.
There is no public exploit known, and it is not in the CISA KEV. The vulnerability is remotely exploitable.
Update to the latest version of Net2 software and ensure that installation files and source code are protected from unauthorized access.
Technical Analysis
CVE-2023-43870 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
