Descriptions

LAquis SCADA Versions 4.1.0.3870 and prior has several out-of-bounds read vulnerabilities, which may allow remote code execution.

LAquis SCADA en versiones 4.1.0.3870 y anteriores tiene varias vulnerabilidades de lectura fuera de límites que podrían permitir la ejecución remota de código.

This vulnerability allows remote attackers to disclose sensitive information 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 LQS files. The issue results from the lack of proper validation of user-supplied data, which can result in a read before an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
