Improper Certificate Validation

CVE-2025-66001

High
8.8/10

Summary

NeuVector supports login authentication through OpenID Connect. However, the TLS verification (which verifies the remote server's authenticity and integrity) for OpenID Connect is not enforced by default. As a result this may expose the system to Man-in-the-Middle (MITM) attacks. Versions from 5.3.0 prior to 5.4.8 are affected.

CWE-295 - Improper Certificate Validation

The authenticity component of a web system stems from the ability to validate “Digital certificates”, which (i) establish trust between two or more entities sharing data over a network; (ii) ensure data at rest and transit is secure from unauthorized access; and (iii) check the identity of the actors that interact with the system. An application with absent or ineffective certificate validation mechanisms allows malicious users, impersonating trusted hosts, to manipulate the communication path between the client and the host, resulting in unauthorized access to data and to the application’s internal environment, and potentially enabling man-in-the-middle attacks.
