Overview

The Rockwell ControlLogix 1756-ENBT/A EtherNet/IP Bridge web interface contains a URL redirection vulnerability.

Description

The Rockwell Logix Automation ControlLogix 1756-ENBT/A EtherNet/IP Bridge uses a web interface to display log files and status information. This web interface contains a URL redirection vulnerability. To exploit this issue, an attacker would need to convince an operator to open on a specially crafted URL.

Impact

An attacker may be able to redirect a user's browser to an another website.

Solution

We are currently unaware of a practical solution to this problem. Until updated firmware is available, we recommend that administrators implement the below workaround.

Do not allow remote access

If no Internet connectivity is allowed (including access through email, proxies or firewalls) to the operator's computer, an attacker will not be able to remotely exploit this issue. See Rockwell's Reference Architectures for Manufacturing site for more information about recommended network architectures.
