Descriptions

LCDS Laquis SCADA prior to version 4.1.0.4150 allows the opening of a specially crafted report format file that may cause an out of bounds read, which may cause a system crash, allow data exfiltration, or remote code execution.

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

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 parsing of LGX 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 buffer. An attacker can leverage this vulnerability to execute code in the context of the process.
