VULNERABILITY DETAILS	This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Moxa SoftCMS. 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 AudioRecord method in the RTSPVIDEO ActiveX control. The implementation copies the user-supplied string for the fullfilename parameter to a fixed-size heap buffer without validating its size, which can lead to a buffer overflow. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.
