TITLE
V-Simulator and V-Server Lite Out-of-bounds Vulnerability in Microsoft
Trust: 0.8
DESCRIPTION
Multiple stack-based buffer overflow issues have been identified in the way the application processes project files, allowing an attacker to craft a special project file that may allow arbitrary code execution on the Tellus Lite V-Simulator and V-Server Lite (versions prior to 4.0.10.0). V-Simulator and V-Server Lite Is vulnerable to an out-of-bounds write.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fuji Electric V-Server Lite. 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 VPR files. The issue results from the lack of proper validation of 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. Fuji Electric Tellus Lite V-Simulator and Fuji Electric V-Server Lite are both products of Fuji Electric, Japan. The software can collect information about PLCs, temperature controllers, inverters and other equipment
