Moxa SoftCMS RTSPVIDEO.rtspvideoCtrl.1 Open and Open2 Remote Code Execution Vulnerability

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 Open and Open2 methods in the RTSPVIDEO ActiveX control. The implementation copies a user-supplied string into a fixed-length 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.
