ibaPDA and ibaDatCoordinator Deserialization Vulnerability Allows Full System Access.

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-8024

A deserialization vulnerability in ibaPDA or ibaDatCoordinator allows remote, unauthenticated attackers to gain full system access. This means an attacker could potentially control the affected systems without needing any credentials. The primary concern is to determine if these systems are in use and reachable, as the

The affected software, ibaPDA and ibaDatCoordinator, is typically used in industrial automation, process data acquisition, and control environments. These systems are generally deployed within isolated operational technology or internal enterprise networks and are not intended to be exposed to the public internet.

Horizon Alert

Summary of the vulnerability and why it matters

A remote attacker could gain full system access by exploiting a vulnerability in ibaPDA or ibaDatCoordinator software. This issue allows an unauthenticated attacker to execute code on affected systems without needing prior access or credentials. The primary concern is confirming whether these systems are in use and exposed, as this type of software is often found in industrial or internal networks.

Attack Path

How an attacker could exploit the issue

A remote attacker can send specially crafted data to the ibaPDA or ibaDatCoordinator components. This data triggers a vulnerability related to the handling of untrusted data during deserialization, potentially allowing the attacker to gain complete control over the affected system.

No authentication or network access needed.
Deserialization of untrusted data.
Full system access gained by attacker.

Live Threat

Current exploitation, exposure, and threat context

A remote, unauthenticated attacker could gain full access to ibaPDA or ibaDatCoordinator systems by exploiting a deserialization vulnerability when processing untrusted data. This could affect the confidentiality, integrity, and availability of the affected systems.

Full system compromise.

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability in ibaPDA or ibaDatCoordinator requires a coordinated effort between application owners and potentially infrastructure or platform teams. The first critical step is to accurately inventory all instances of the affected technology, verify their exposure and business criticality, and then engage with the accountable owner to prioritize and plan remediation.

Application owners must triage exposure.
Verify system reachability and criticality.
Plan risk-based remediation activities.

Frequently asked questions

What is ibaPDA and ibaDatCoordinator?

These software components are used for process data acquisition and industrial automation. They collect, record, and analyze data from various control systems, serving as a vital bridge between machinery and analytical tools in manufacturing and engineering environments.

What does deserialization of untrusted data mean for CVE-2026-8024?

This vulnerability, classified as CWE-502, occurs when the software takes data from an untrusted source and attempts to reconstruct it into an object without sufficient validation. Because the application blindly trusts this incoming information, an attacker can manipulate the data structure to force the system to execute arbitrary commands, leading to full system compromise.

How is this vulnerability triggered?

An attacker triggers this flaw by sending specially crafted, malicious data to the ibaPDA or ibaDatCoordinator software. The vulnerability is not triggered by standard operational traffic or legitimate data logging; it requires the successful delivery of this specific, malicious payload to the application component.

Do I need to worry about CVE-2026-8024?

According to Halo Surface Signal, these tools are generally deployed within isolated industrial or internal networks and are not intended for public internet access. Your risk level is significantly lower if your instances are not reachable from outside your controlled network environment.

When should I take action to secure my systems?

You should begin by creating a comprehensive inventory of all ibaPDA and ibaDatCoordinator installations in your environment. Once you have identified these assets, verify their network reachability to determine which are exposed and prioritize those systems for remediation in coordination with your application owners.
