TITLE

Schneider Electric Made Interactive Graphical SCADA System Multiple vulnerabilities in

Trust: 0.8

sources: JVNDB: JVNDB-2020-009593

DESCRIPTION

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. 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 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. IGSS version 14.0.0.20247 and earlier have a buffer overflow vulnerability. The vulnerability stems from inappropriate restrictions on operations within the memory buffer boundary
