Descriptions

A Path Traversal issue was discovered in Advantech WebAccess/SCADA versions prior to V8.2_20170817. An attacker has read access to files within the directory structure of the target device.

Se ha descubierto un problema de salto de directorio en Advantech WebAccess/SCADA en versiones anteriores a la V8.2_20170817. Un atacante tiene acceso de lectura a archivos en la estructura de directorio del dispositivo objetivo.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of the filename parameter of certUpdate.asp. The issue results from the lack of proper validation of user-supplied data, which can allow for the upload of arbitrary files. An attacker can leverage this vulnerability to execute code under the context of the current process.
