CVE-2026-31985Disabled and non-configurable TLS certificate validation in n2os-tui when connecting the Remote Collector to a Guardian or CMC, in Remote Collector before v26.2.0
High 8.1
In plain English
A high-severity security flaw in Remote Collector from Nozomi Networks. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 10% of all known vulnerabilities).
Official description
When 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.
