Security readout for executives and security teams
Plain-English summary
CVE-2020-15351 is a local privilege escalation issue in IDrive for Windows before 6.7.3.19. The installer used weak folder permissions while a related service ran with SYSTEM privileges, so a normal Windows user could potentially gain full control of the endpoint.
Executive priority
Treat this as a high-priority endpoint hardening issue where IDrive is deployed. It does not appear remotely exploitable from the provided evidence, but it can turn limited local access into full SYSTEM control.
Technical view
IDrive for Windows before 6.7.3.19 installed under %PROGRAMFILES(X86)%\IDriveWindows with Authenticated Users modify permissions inherited to contents and subfolders. The IDriveService ran as LocalSystem. The combination allowed a local standard user to replace service-controlled content and escalate to NT AUTHORITY\SYSTEM.
Likely exposure
Exposure is limited to Windows systems running IDrive versions before 6.7.3.19, especially default installations in the IDriveWindows program directory. The source bundle does not identify affected CPEs, enterprise deployment scale, or non-Windows impact.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires local access as a standard authenticated Windows user, so the main risk is post-compromise privilege escalation or insider misuse on endpoints running vulnerable IDrive.
Researcher notes
The key condition is the combination of writable installation content and a LocalSystem service. Evidence is clear on the vulnerable permission model and version boundary, but incomplete on CVSS, CWE mapping, affected CPEs, exploit prevalence, and exact vendor remediation details.
Mitigation direction
- Update IDrive for Windows to 6.7.3.19 or later.
- Review IDrive vendor release guidance before applying manual workarounds.
- Restrict local user write access to IDrive installation paths where operationally safe.
- Remove vulnerable IDrive installations from systems where the software is no longer required.
Validation and detection
- Inventory Windows endpoints for IDrive installations and installed versions.
- Identify installs earlier than 6.7.3.19 for remediation tracking.
- Review the IDriveWindows directory permissions for broad modify rights.
- Confirm IDriveService configuration and service account on affected endpoints.
