Summary

CVE-2019-25288 is a high-severity Unquoted Search Path or Element (CWE-428) vulnerability in Wacom WTabletService (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 5th 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 RA-5 (Vulnerability Monitoring and Scanning) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2019-25288 is an unquoted service path vulnerability in Wacom WTabletService version 6.6.7-3. This flaw occurs when the Windows service executable path is not properly quoted, allowing local attackers to hijack the service by placing a malicious executable in a directory preceding the legitimate service binary in the system's search path.

Local attackers with low privileges can exploit this vulnerability by inserting a malicious executable file into the service path. Upon service restart or system reboot, the malicious code executes with elevated privileges, potentially granting high-impact confidentiality, integrity, and availability compromises as scored by CVSS 3.1 vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H (base score 7.8). The issue maps to CWE-428 (Unquoted Search Path or Element).

Advisories and references, including an Exploit-DB entry (exploit 47593) providing proof-of-concept code, a VulnCheck advisory detailing the unquoted service path in WTabletService and WTabletServicePro, and the Wacom vendor site, highlight the vulnerability but do not specify patches in the available information. Security practitioners should verify service paths and apply any vendor updates from Wacom.
