Title
Grid Protection Alliance openPDC and openHistorian Use of Externally-Controlled Input to Select Classes or Code
Summary
A component loading mechanism in openPDC and openHistorian will construct and run any specified type, which may be an invalid component to load. An attacker with an authenticated user account and the ability to place a file on the host filesystem can use this to run arbitrary constructor code, and this code runs with the privileges of the affected service account.

Title
Grid Protection Alliance openPDC and openHistorian Server-Side Request Forgery (SSRF)
Summary
A Modbus connection feature on openPDC accepts a caller-specified destination address and port with no restriction on which internal hosts may be targeted. An authenticated user can attempt connections to arbitrary internal network destinations, revealing which destinations are reachable. With repeated attempts, an attacker may be able to map the internal network.

Title
Grid Protection Alliance openPDC and openHistorian Deserialization of Untrusted Data
Summary
A service console interface on openPDC and openHistorian deserializes a client-supplied data structure. On systems using Windows Authentication, an attacker must already be authenticated to reach this function; on systems without Windows Authentication, this is reachable by an unauthenticated network attacker. This allows an attacker to trigger deserialization of an arbitrary object graph, which could allow remote code execution under the privileges of the affected service account.

Title
Grid Protection Alliance openPDC and openHistorian Use of Externally-Controlled Input to Select Classes or Code
Summary
A component loading mechanism in openPDC and openHistorian will construct and run any specified type, which may be an invalid component to load. An attacker with an authenticated user account and the ability to place a file on the host filesystem can use this to run arbitrary constructor code, and this code runs with the privileges of the affected service account.

Title
Grid Protection Alliance openPDC and openHistorian Server-Side Request Forgery (SSRF)
Summary
A Modbus connection feature on openPDC accepts a caller-specified destination address and port with no restriction on which internal hosts may be targeted. An authenticated user can attempt connections to arbitrary internal network destinations, revealing which destinations are reachable. With repeated attempts, an attacker may be able to map the internal network.

Title
Grid Protection Alliance openPDC and openHistorian Deserialization of Untrusted Data
Summary
A service console interface on openPDC and openHistorian deserializes a client-supplied data structure. On systems using Windows Authentication, an attacker must already be authenticated to reach this function; on systems without Windows Authentication, this is reachable by an unauthenticated network attacker. This allows an attacker to trigger deserialization of an arbitrary object graph, which could allow remote code execution under the privileges of the affected service account.
