Description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of LAquis SCADA. 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 aq.exe. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this functionality to execute code in the context of the current process.
