Summary

CVE-2019-25271 is a high-severity Unquoted Search Path or Element (CWE-428) vulnerability in Netgate (inferred from references). Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception by Unquoted Path (T1574.009); ranked at the 25th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

CVE-2019-25271 is an unquoted service path vulnerability in NETGATE Data Backup version 3.0.620, specifically affecting the NGDatBckpSrv Windows service configuration. Published on 2026-02-05, this issue falls under CWE-428 and carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high impact potential from local access.

A local attacker with low privileges can exploit the unquoted path by placing malicious executable files in specific directory locations traversed by the service. Successful exploitation allows injection and execution of arbitrary code with LocalSystem privileges, enabling full system compromise including high confidentiality, integrity, and availability impacts.

Advisories and related resources include the vendor site at http://www.netgate.sk/, a proof-of-concept exploit at https://www.exploit-db.com/exploits/47746, and a VulnCheck advisory at https://www.vulncheck.com/advisories/netgate-data-backup-ngdatbckpsrv-unquoted-service-path, which detail the vulnerability and exploitation methods.

MITRE ATT&CK Enterprise TechniquesAI

T1574.009 Path Interception by Unquoted Path Stealth
Adversaries may execute their own malicious payloads by hijacking vulnerable file path references.
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Unquoted service path directly matches T1574.009 Path Interception by Unquoted Path; exploitation yields SYSTEM-level code execution, mapping to T1068 Exploitation for Privilege Escalation.
