Vulnerability from variot

An issue was discovered in WECON Technology LEVI Studio HMI Editor v1.8.29 and prior. Specially-crafted malicious files may be able to cause stack-based buffer overflow vulnerabilities, which may allow remote code execution. WECON Technology LEVI Studio HMI Editor Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable 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 in the handling of LeviStudioU Project files. When providing an overly long MulStatus szFilename XML 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 under the context of the current process. LeviStudio HMI Editor is an editor in the human-machine interface of Wecon Technologies of China. Failed exploit attempts will likely cause denial-of-service conditions
