Descriptions

LCDS Laquis SCADA prior to version 4.1.0.4150 allows execution of script code by opening a specially crafted report format file. This may allow remote code execution, data exfiltration, or cause a system crash.

LCDS Laquis SCADA, en versiones anteriores a la 4.1.0.4150, permite la ejecución de código script abriendo un archivo de formato de informe especialmente manipulado. Esto podría permitir la ejecución remota de código, la exfiltración de datos o provocar el cierre inesperado del sistema.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of LAquis SCADA Software. 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 processing of LGX report files. Script embedded in a crafted file can create files in arbitrary locations using the File.BlockWrite method. An attacker can leverage this vulnerability to execute code in the context of the current user.
