Description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.
