ZDI-CAN-14578: WECON LeviStudioU UMP FIle Parsing HmiSet Tag Type Stack-based Buffer Overflow Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on affected installations of WECON LeviStudioU. 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 parsing of HmiSet tags within UMP files. When parsing the Type attribute, 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 in the context of the current process.
