CVE-2016-20092

NetDrive 2.6.12 Unquoted Service Path Elevation of Privilege

Published Jun 19, 2026 CVSS 4.0 · 8.5 High EPSS < 1% KEV · Not listed

Description

NetDrive 2.6.12 contains an unquoted service path vulnerability in the Netdrive2_Service_Netdrive2 service that allows local users to execute arbitrary code with SYSTEM privileges. Attackers can insert malicious executables in the system root path that will be executed during service startup or system reboot, resulting in privilege escalation.

Analysis

Technical impact

NetDrive 2.6.12 has an unquoted service path in the Netdrive2_Service_Netdrive2 service. Because the executable path is not surrounded by quotation marks, the Windows service loader may misinterpret the path, allowing a local user to place a malicious executable in the system root directory; the service will launch it with SYSTEM privileges during startup or reboot, giving the attacker full control of the machine. The weakness is a classic unquoted service path flaw (CWE-428) that enables arbitrary code execution with elevated rights.

Affected Systems

The affected product is NetDrive, version 2.6.12. It is distributed by NetDrive. No other versions or platforms are listed.

Risk and Exploitability

The CVSS score of 8.5 indicates severe risk, while the EPSS score is unavailable and the vulnerability is not listed in CISA KEV. The likely attack vector is local: a user who can run programs on the machine may create the malicious file in the system root directory or gain write access to the root path. Once the service restsarts or the system reboots, the attacker’s code runs with SYSTEM privileges, enabling full control, data tampering, and persistence.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade to the latest NetDrive release that includes a quoted service path.
Modify the service configuration to quote the executable path or reference a non‑writable directory.
Restrict local user permissions by denying write access to the system root directory.
Set ACLs on the system root folder to allow write access only for administrators.
