Descriptions

Stack-based buffer overflow may occur when Fuji Electric Tellus Lite V-Simulator parses a specially-crafted input file.

Puede producirse un desbordamiento del bĂșfer basado en pila cuando Fuji Electric Tellus Lite V-Simulator analiza un archivo de entrada especialmente manipulado.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fuji Electric Tellus 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 processing of V9 files by the V-Simulator 6 module. 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.

*Credits: Fritz Sands and kimiya working with Trend Micro Zero Day Initiative reported these vulnerabilities to CISA.
