New! Plugin Severity Now Using CVSS v3

The AVEVA InduSoft Web Studio or InTouch Edge HMI (formerly InTouch Machine Edition) is affected by a remote code execution vulnerability.


The AVEVA InduSoft Web Studio (IWS) or InTouch Edge HMI (formerly InTouch Machine Edition) running on the remote host is affected by a remote code execution vulnerability due to multiple flaws in the TCPIP server listening on the default ports 1234 and 51234. Specifically, the server does not require authentication for command 66 received from a remote client and it can be instructed to read a database connection configuration file from an external host. An unauthenticated, remote attacker can exploit this issue, via a specially crafted message, to execute arbitrary code under the privileges of the IWS or InTouch Edge HMI runtime.


Apply InduSoft Web Studio v8.1 SP3 or later / InTouch Edge HMI (formerly InTouch Machine Edition) 2017 Update 3 or later.
