Foxit Reader 2.3 before Build 3902 and 3.0 before Build 1506, including 1120 and 1301, does not require user confirmation before performing dangerous actions defined in a PDF file, which allows remote attackers to execute arbitrary programs and have unspecified other impact via a crafted file, as demonstrated by the "Open/Execute a file" action.
