AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess/HMI Designer. 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 the parsing of PM3 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
