Trust: 0.8

sources: JVNDB: JVNDB-2020-009593

DESCRIPTION

A CWE-787 Out-of-bounds Write vulnerability exists in IGSS Definition (Def.exe) version 14.0.0.20247 that could cause Remote Code Execution when malicious CGF (Configuration Group File) file is imported to IGSS Definition. Interactive Graphical SCADA System (IGSS) Is Schneider Electric Software for monitoring and controlling control systems provided by the company. 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 user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process
