Descripción técnica

An improper certificate/host key validation vulnerability was discovered in the Smart Polling functionality, which established encrypted connections to target devices without validating the remote host's identity, and no option was provided to enable it. A man-in-the-middle attacker positioned between a sensor and a polled device can, during a polling session, impersonate the device and intercept the communication, including the credentials used to access it. The captured credentials can then be replayed to authenticate against the device itself or against other devices sharing the same credentials, allowing the attacker to access and tamper with the device's data and to disrupt its operations.

——3When the upstream Guardian or CMC was configured in the Remote Collector via n2os-tui, the generated configuration disabled TLS certificate verification, and no option was provided to enable it. A malicious actor could perform a man-in-the-middle attack and intercept the communication between the Remote Collector and the Guardian or CMC. This could result in theft of the sync token, impersonation of the server, injection of spoofed data (such as false asset information or vulnerabilities) into the Guardian or CMC, or disruption of the data flow between the Remote Collector and the Guardian or CMC.61d
