Synopsis

The remote host is running a SCADA application that is affected by an arbitrary file download vulnerability.

Description

The Advantech WebAccess/SCADA Network Service (webvrpcs.exe) running on the remote host is affected by an arbitrary file download vulnerability due to improper validation of user-supplied data when processing a DCERPC request. An unauthenticated, remote attacker can exploit this, via a series of crafted requests, to download arbitrary files and disclose sensitive information.
