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 Open3 method of the RTSPVIDEO.rtspvideoCtrl.1 control. The implementation copies the user-supplied string to a field in a heap-based buffer without validating the size of the string, which can lead to a heap-based buffer overflow. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.
