Summary
CVE-2019-25293 is a high-severity Unquoted Search Path or Element (CWE-428) vulnerability. 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 2.7th 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 are NIST 800-53 CM-6 (Configuration Settings) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2019-25293 is an unquoted service path vulnerability in BlueStacks App Player version 2.4.44.62.57, specifically affecting the BstHdLogRotatorSvc service. The issue arises from an unquoted path to C:\Program Files (x86)\Bluestacks\HD-LogRotatorService.exe, classified as CWE-428, with 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). Published on 2026-02-06, it enables local attackers to potentially execute arbitrary code.
Local attackers with low privileges can exploit the unquoted service path by placing malicious executables in locations that the Windows service control manager resolves before the legitimate binary. Successful exploitation allows privilege escalation, granting high confidentiality, integrity, and availability impacts.
