Descriptions

Opening a specially crafted LCDS LAquis SCADA before 4.3.1.71 ELS file may result in a write past the end of an allocated buffer, which may allow an attacker to execute remote code in the context of the current process.

Abrir un archivo ELS especialmente manipulado de LCDS LAquis SCADA, en versiones anteriores a la 4.3.1.71, podría resultar en una lectura más allá del final de un búfer asignado, lo que podría permitir que un atacante ejecute código remoto en el contexto del proceso actual.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of LAquis SCADA. 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 handling of ELS 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 current process.
