Descriptions

Processing a specially crafted project file in LAquis SCADA 4.3.1.71 may trigger an out-of-bounds read, which may allow an attacker to obtain sensitive information. The attacker must have local access to the system. A CVSS v3 base score of 2.5 has been calculated; the CVSS vector string is (AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).

El procesamiento de un archivo de proyecto especialmente diseñado en LAquis SCADA versión 4.3.1.71, puede desencadenar una lectura fuera de límites, lo que puede permitir a un atacante obtener información confidencial. El atacante requiere tener acceso local al sistema. Un puntaje base de CVSS v3 de 2.5 ha sido calculado; la cadena de vectores CVSS es (AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).

This vulnerability allows remote attackers to disclose sensitive information 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 read before the start of an allocated data structure. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
