Details

The specific flaw exists within the trusted certification feature. The issue lies in the handling of the OpcUaSecurityCertificateAuthorityTrustDir variable, which allows an arbitrary file write with attacker-controlled data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-20537.

Severity

7.2 (High)
