Description

Triangle MicroWorks SCADA Data Gateway Trusted Certification Unrestricted Upload of File Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Triangle MicroWorks SCADA Data Gateway. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
