Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-26697	DTOO309 - InfoPath	SV-34226r1_rule	ECSC-1	Medium

Description
InfoPath 2010 forms' business logic can only call into Global Assembly Cache (GAC) assemblies listed in the APTCA Assembly Allowable List. If this configuration is changed, forms can call into any assembly in the GAC where the Allow Partially Trust Callers Attribute (APTCA) is set. This configuration could allow malicious developers to access assemblies in the GAC not intended to be used by InfoPath forms.
