Descriptions

A CWE-787: Out-of-bounds Write vulnerability exists in Interactive Graphical SCADA System (IGSS), Version 14 and prior, which could cause a software crash when data in the mdb database is manipulated.

Una CWE-787: Existe una vulnerabilidad de escritura fuera de límites en Interactive Graphical SCADA System (IGSS), versión 14 y anteriores, que podría causar un bloqueo del software cuando son manipulados los datos en la base de datos mdb.

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 use of the UnitIdx data in the BaseUnits table. 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 buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
