Descriptions

Advantech iView, versions 5.6 and prior, is vulnerable to multiple path traversal vulnerabilities that could allow an attacker to create/download arbitrary files, limit system availability, and remotely execute code.

Advantech iView, versiones 5.6 y anteriores, es vulnerable a vulnerabilidades de múltiples caminos que podrían permitir a un atacante crear/descargar archivos arbitrarios, limitar la disponibilidad del sistema y ejecutar código de forma remota.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech iView. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the processing of calls to the exportLinks method of the LinksTable class. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of SYSTEM.
