Descriptions

WebAccess/NMS (versions prior to 3.0.2) does not properly sanitize user input and may allow an attacker to inject system commands remotely.

WebAccess/NMS (versiones anteriores a 3.0.2), no sanea apropiadamente una entrada del usuario y puede permitir a un atacante inyectar comandos del sistema remotamente.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess/NMS. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the processing of calls to the ManualDBBackup endpoint. When parsing the filenamebknow parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
