Executive Summary

CVE-2026-8024 is a critical deserialization vulnerability affecting ibaPDA versions below 8.14.0 and ibaDatCoordinator versions below 4.0.7.

The flaw arises from improper handling of .NET BinaryFormatter deserialization, which allows a remote, unauthenticated attacker to exploit type confusion.

This exploitation can lead to arbitrary code execution with the privileges of the service user account, potentially resulting in full system compromise.

Impact Analysis

This vulnerability allows a remote, unauthenticated attacker to execute arbitrary code on the affected system without any user interaction or privileges.

Because the attacker can run code with the service user account privileges, it may lead to full system compromise, including unauthorized access, data manipulation, and disruption of services.

Detection Guidance

The vulnerability affects ibaPDA versions below 8.14.0 and ibaDatCoordinator versions below 4.0.7 due to improper deserialization of untrusted data. Detection involves identifying if these vulnerable versions are running on your systems.

You can check the installed versions of ibaPDA and ibaDatCoordinator on your systems using commands that query installed software versions or service versions.

• On Windows, use PowerShell to check installed versions, for example: Get-ItemProperty 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*' | Where-Object { $_.DisplayName -like '*ibaPDA*' -or $_.DisplayName -like '*ibaDatCoordinator*' } | Select-Object DisplayName, DisplayVersion
• Alternatively, check the version of running services or executables directly, e.g., by inspecting file properties or using commands like: (Get-Command 'C:\Path\To\ibaPDA.exe').FileVersionInfo

Network detection can involve monitoring for unusual or unauthorized remote connections to these applications, especially from unauthenticated sources, but no specific detection commands are provided.

Mitigation Strategies

Immediate mitigation steps include restricting network connections to the affected applications to localhost only and configuring Windows Firewall rules to block or remove incoming connections to ibaPDA and ibaDatCoordinator.

• Restrict connections to localhost to prevent remote exploitation.
• Adjust Windows Firewall settings to remove or deactivate incoming rules for the vulnerable applications.
• Create manual firewall rules to allow only necessary ports and block others.

The recommended long-term remediation is to update to ibaPDA version 8.14.0 or ibaDatCoordinator version 4.0.7, which contain patches addressing this vulnerability.

Compliance Impact

CVE-2026-8024 allows a remote, unauthenticated attacker to execute arbitrary code and gain full access to affected systems, potentially compromising confidentiality, integrity, and availability of data.

Such a critical security breach could lead to violations of data protection regulations like GDPR and HIPAA, which require safeguarding sensitive personal and health information against unauthorized access and ensuring system integrity.

Therefore, organizations using affected versions of ibaPDA or ibaDatCoordinator must apply recommended patches or mitigations promptly to maintain compliance with these standards.
