Descriptions

A type confusion vulnerability may be exploited when LAquis SCADA 4.3.1.71 processes a specially crafted project file. This may allow an attacker to execute remote code. The attacker must have local access to the system. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

Una vulnerabilidad de confusión de tipo puede ser explotada cuando LAquis SCADA versión 4.3.1.71, procesa un archivo de proyecto especialmente diseñado. Esto puede permitir que un atacante ejecute código remoto. El atacante requiere tener acceso local al sistema. Un puntaje base de CVSS v3 de 7.8 ha sido calculado; la cadena de vectores CVSS es (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

This vulnerability allows remote attackers to execute arbitrary code on affected 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 parsing of LQS files. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process.
