Inductive Automation Ignition Vulnerabilities

Low RiskICS-CERT ICSA-15-090-01Jan 1, 2015
Summary

Inductive Automation Ignition 7.7.2 contains an input validation vulnerability (CWE-916) that could allow an attacker with network access to gain unauthorized access to the gateway. This vulnerability affects the integrity and availability of SCADA and MES systems that rely on Ignition for real-time process monitoring and control.

What this means
What could happen
An attacker with network access to an Ignition 7.7.2 installation could exploit this vulnerability to gain unauthorized access or control over the SCADA/MES system, potentially disrupting production monitoring and process control.
Who's at risk
Manufacturing facilities, water utilities, and electric utilities using Inductive Automation Ignition 7.7.2 for SCADA monitoring and process control. Specifically affects any organization using this version for real-time production data collection and operator interfaces.
How it could be exploited
An attacker would need to reach the Ignition gateway on the network and exploit the vulnerability related to improper neutralization of input (CWE-916) to gain unauthorized access or execute operations on the system without proper authorization.
Prerequisites
  • Network access to the Ignition gateway port (typically 8088 or 8089)
  • Ignition version 7.7.2 deployed in the environment

0/1

Patching may require device reboot — plan for process interruption

HOTFIXUpgrade Ignition to a patched version newer than 7.7.2 if available from vendor
Mitigations - no patch available
0/1
Ignition: 7.7.2 has reached End of Life. The vendor will not release a patch. Apply the following compensating controls:
HARDENINGImplement network segmentation to isolate the Ignition gateway from untrusted networks and limit lateral movement from compromised devices
