Galil RIO-47100 Improper Input Validation

Act NowICS-CERT ICSA-13-116-01Jan 28, 2013
Summary

The Galil RIO-47100 PLC contains an improper input validation vulnerability (CWE-20) in all versions. The device does not adequately check or sanitize network inputs before processing them, which could allow an attacker on the network to send malformed commands or data packets that cause the device to malfunction or stop responding. No security patches are available from the vendor for this product.

What this means
What could happen
An attacker with network access to the RIO-47100 PLC could send malformed input to cause a denial of service, potentially stopping industrial processes or data collection on connected systems.
Who's at risk
Manufacturing facilities using Galil RIO-47100 PLCs for process control, motion control, or data acquisition should implement protective measures immediately. This is especially critical for facilities where unplanned stops or process interruptions could cause safety hazards or significant downtime.
How it could be exploited
An attacker on the network sends specially crafted commands or data packets to the RIO-47100's network interface that bypass input validation. The PLC does not properly check or sanitize these inputs before processing, leading to unexpected behavior or system failure.
Prerequisites
  • Network access to the RIO-47100 PLC
  • Knowledge of the PLC's command or data format

Remediation & Mitigation
0/5
Do now
0/3
HARDENINGImplement network segmentation to restrict access to the RIO-47100 PLC from untrusted networks (e.g., place the PLC on a separate VLAN with firewall rules limiting connections to authorized engineering workstations and systems only)
WORKAROUNDDeploy a host-based firewall or network appliance in front of the PLC to filter and validate incoming network traffic before it reaches the device
HARDENINGDisable any non-essential network services or access methods on the RIO-47100 if supported by the device firmware
Mitigations - no patch available
0/2
RIO-47100 PLC: vers:all/* has reached End of Life. The vendor will not release a patch. Apply the following compensating controls:
HARDENINGMonitor network traffic to and from the RIO-47100 for anomalous patterns or malformed packets that could indicate exploitation attempts
HARDENINGContact Galil Motion Control to confirm end-of-life status and discuss long-term replacement plans, as no security patches are available for this product
