This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Wecon LeviStudioU UserManage. 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 handling of the UserMgr.xml file. When parsing the GroupList Description element, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of Administrator.
A remote code execution vulnerability exists in the way that the VBScript engine handles objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system.
