Descriptions

A CWE-125: Out-of-bounds read vulnerability exists inIGSS Definition (Def.exe) V15.0.0.21140 and prior that could result in loss of data or remote code execution due to missing length checks, when a malicious WSP file is being parsed by IGSS Definition.

Un CWE-125: Se presenta una vulnerabilidad de lectura fuera de límites en IGSS Definition (Def.exe) versiones V15.0.0.21140 y anteriores, que podría resultar en la pérdida de datos o una ejecución de código remota debido a una falta de comprobaciones de longitud, cuando un archivo WSP malicioso está siendo analizado por IGSS Definition

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 WSP files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
