This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of WECON LeviStudio. 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 in the handling of LeviStudio Project files. By providing an overly long HmiSet Style XML attribute, an attacker can overflow a stack-based buffer and execute arbitrary code in the context of the current process.
