A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v1.0 for Windows could allow an authenticated, local attacker to run arbitrary code with elevated privileges. The PIA client is vulnerable to a DLL injection vulnerability during the software update process. The updater loads several libraries from a folder that authenticated users have write access to. A low privileged user can leverage this vulnerability to execute arbitrary code as SYSTEM.

Security readout for executives and security teams

Plain-English summary

CVE-2019-12574 is a local privilege escalation in Private Internet Access VPN Client v1.0 for Windows. A low-privileged local user could abuse the updater’s library-loading behavior to run code as SYSTEM. This is most urgent where shared Windows workstations, helpdesk endpoints, or lower-trust users have local access.

Executive priority

Treat this as high priority on endpoints where non-admin users can log in locally. It can turn ordinary local access into SYSTEM control, but current evidence does not show remote exploitation or confirmed active exploitation.

Technical view

The PIA Windows client updater loads libraries from a directory writable by authenticated users. That creates a DLL injection path during update execution, allowing arbitrary code to run with SYSTEM privileges. The sources identify PIA VPN Client v1.0 for Windows, but do not provide CVSS, CWE, broad affected-version ranges, or a named fixed version.

Likely exposure

Exposure appears limited to Windows systems running London Trust Media Private Internet Access VPN Client v1.0. The provided CVE data has incomplete affected-product metadata, so teams should validate actual installed versions rather than assume broader or narrower impact.

Exploitation context

The source describes authenticated local exploitation requiring a low-privileged user on the Windows host. The CVE is not listed as KEV in the provided bundle, and no cited source here supports active exploitation in the wild.

Researcher notes

The public record is sparse: one referenced advisory describes the updater DLL-loading issue, while CVE metadata lacks CVSS, CWE, and structured affected CPEs. Validation should focus on installed version, Windows platform, updater behavior, and writable library search paths without assuming unsupported version ranges.

Mitigation direction

  • Inventory Windows endpoints for Private Internet Access VPN Client v1.0.
  • Check PIA or London Trust Media guidance for fixed versions or removal instructions.
  • Upgrade or remove affected clients where vendor guidance confirms remediation.
  • Review updater directory permissions before applying any compensating control.
  • Monitor endpoint alerts for suspicious SYSTEM-level activity involving the PIA updater.

Validation and detection

  • Confirm whether PIA VPN Client v1.0 is installed on Windows endpoints.
  • Review updater-related directories for authenticated-user write access.
  • Verify any deployed update matches vendor remediation guidance.
  • Check EDR logs for unusual SYSTEM processes around PIA update activity.
  • Document exceptions where affected software remains installed.
