https://notcve.org/view.php?id=CVE-2020-7550
A CWE-119 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability exists in IGSS Definition (Def.exe) version 14.0.0.20247 and prior that could cause Remote Code Execution when malicious CGF (Configuration Group File) file is imported to IGSS Definition. Se presenta una vulnerabilidad de Restricción Inapropiada de Operaciones dentro de los Límites de un Búfer de Memoria CWE-119 en IGSS Definition (Def.exe) versión 14.0.0.20247 y anteriores que podría causar una Ejecución de Código Remota cuando se importa un archivo CGF (Configuration Group File) malicioso a IGSS Definición This vulnerability allows remote attackers to execute arbitrary code on affected installations of Schneider Electric IGSS. 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 CGF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. • https://www.se.com/ww/en/download/document/SEVD-2020-315-03 https://www.zerodayinitiative.com/advisories/ZDI-21-092 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
