Summary

CVE-2025-58066 is a medium-severity Network Amplification (CWE-406) vulnerability. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Network Denial of Service (T1498); ranked at the 26th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-5 (Denial-of-service Protection) and SI-4 (System Monitoring) — see the control section below for these in your framework.

Vulnerability Data

nptd-rs is a tool for synchronizing your computer's clock, implementing the NTP and NTS protocols. In versions between 1.2.0 and 1.6.1 inclusive servers which allow non-NTS traffic are affected by a denial of service vulnerability, where an attacker can induce…

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Denial-of-service protection directly requires mechanisms to limit excessive outbound traffic volume that amplification attacks exploit.

System monitoring detects anomalous traffic volumes indicative of amplification after the weakness is present.

Boundary protection at managed interfaces enforces controls on communications volume and flow that can stop amplification.

DE.CM-01 mostly match
prevents

Network monitoring directly detects anomalous traffic volumes that indicate amplification abuse.

PR.IR-04 partial match
prevents

Bandwidth monitoring supports capacity planning that can surface volume problems but does not enforce message-volume controls.

finds

Monitoring activities can detect anomalous traffic volumes, yet detection alone does not enforce control.

A.8.15 Logging partial match
finds

Logging provides visibility into high-volume traffic but does not itself limit or control it.

mitigates

Network security controls include traffic filtering and rate-limiting that prevent amplification attacks.

mitigates

Security of network services can impose volume controls on specific services, but does not address the weakness broadly.

degrades

Capacity management directly limits excessive outbound traffic that an actor could otherwise trigger.
