Summary
iba Systems ibaPDA versions prior to 8.12.1 contain an improper file system permissions vulnerability (CWE-732) that allows an attacker with network access to the ibaPDA Server to perform unauthorized file system actions. This could include reading, modifying, or deleting files without authentication. The vulnerability has a CVSS score of 9.8 and affects all confidentiality, integrity, and availability aspects of the system.
What this means
What could happen
An attacker with network access to ibaPDA could perform unauthorized actions on the file system of the server hosting ibaPDA, potentially reading, modifying, or deleting critical data or process files used by the monitoring system.
Who's at risk
Organizations using iba Systems ibaPDA for industrial data acquisition and monitoring. This affects facilities that rely on ibaPDA for real-time process data collection in manufacturing, utilities, and other process industries where unauthorized file system access could compromise data integrity or halt data acquisition.
How it could be exploited
An attacker on the network sends requests directly to the ibaPDA Server (no authentication required). The vulnerability in file system access controls allows the attacker to execute file system operations without proper authorization. The attacker could read sensitive process data, configuration files, or modify/delete files that affect data acquisition and monitoring.
Prerequisites
- Network access to ibaPDA Server port (default port configuration from iba Help Center)
- No authentication required
- ibaPDA version 8.12.0 vulnerable

Remediation & Mitigation
0/6
Do now
0/5HARDENINGConfigure Server Access Manager to restrict connections to only trusted IP addresses (e.g., localhost 127.0.0.1 and specific engineering workstation IPs)
HARDENINGDisable 'Automatically open necessary ports in Windows Firewall' in I/O Manager General settings
HARDENINGDelete or deactivate all existing Windows Firewall incoming rules for ibaPDA Client and Server
HARDENINGManually create Windows Firewall rules to allow only the specific ports and IP addresses required for ibaPDA operation
WORKAROUNDVerify all ibaPDA services and data acquisition functions are operational after applying firewall changes
Schedule — requires maintenance window
0/1Patching may require device reboot — plan for process interruption
HOTFIXUpdate ibaPDA to version 8.12.1 or later
