Summary

Successful exploitation of this vulnerability in PanelView 5510 allows a remote unauthenticated user to gain root privileges on the device. The affected products are PanelView 5510 units with manufacturing dates prior to March 13, 2019 (firmware versions 4.003 or earlier, or 5.002 or earlier). The vulnerability is related to improper access controls (CWE-284). Rockwell Automation recommends updating to v4.003 or later for v4 devices and v5.002 or later for v5 devices. Additionally, network-level mitigations include blocking traffic to ports 2222 and 44818 (TCP/UDP) from outside the manufacturing zone using firewalls or security appliances.

What this means
What could happen
An unauthenticated remote attacker could gain root privileges on the PanelView 5510 display unit, allowing them to modify screen logic, alter process data, or disrupt communication with PLCs and other control equipment in your manufacturing environment.
Who's at risk
Manufacturing facilities and utilities operating PanelView 5510 displays (made before March 13, 2019) in any process control environment—especially water treatment, electric generation, and chemical processing. Any facility using EtherNet/IP or CIP-based control networks with this display unit is at risk if it is exposed to untrusted network segments.
How it could be exploited
An attacker on the network sends a crafted request to the PanelView 5510 via EtherNet/IP or another CIP protocol-based mechanism targeting ports 2222 or 44818. No credentials are required. If the device is not behind a firewall or runs firmware before March 13, 2019, the device grants root access directly.
Prerequisites
  • Network access to port 2222 or 44818 (TCP or UDP)
  • PanelView 5510 manufacturing date before March 13, 2019 with firmware version 4.003 or earlier or version 5.002 or earlier
  • Device not isolated behind a firewall or network access control device

WORKAROUNDBlock inbound traffic to ports 2222 and 44818 (TCP and UDP) from outside the manufacturing zone using firewall rules or network access control devices.
Schedule — requires maintenance window
0/1

Patching may require device reboot — plan for process interruption

HOTFIXUpdate PanelView 5510 firmware to v4.003 or later (for v4 devices) or v5.002 or later (for v5 devices). Plan update during maintenance window to avoid process interruption.
Long-term hardening
0/1
HARDENINGIsolate PanelView 5510 and all control system networks behind a firewall and from the business network. Restrict access from engineering workstations and HMI interfaces to trusted machines only.
