ICS-Park Smart Park Management System Unrestricted File Upload Remote Code Execution.

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-67688

The vulnerability affects a smart park management system, which is typically deployed as a web-based application to manage facility operations. Such management portals are commonly exposed to the internet or wide area networks to allow for remote monitoring, vendor access, and administrative oversight, making the file upload module a likely target for remote network-based exploitation.

Frequently asked questions

What is the ICS-Park Smart Park Management System?

ICS-Park Smart Park Management System is a software platform designed to coordinate and oversee facility operations within parks. It typically functions as a web-based management portal, enabling administrators to monitor infrastructure, manage parking assets, and handle remote oversight tasks through a centralized digital interface.

What does CWE-434 mean regarding CVE-2026-67688?

CWE-434 refers to Unrestricted Upload of File with Dangerous Type. This means the software fails to properly check or limit the types of files users can upload. In the context of CVE-2026-67688, this weakness allows an attacker to bypass intended security controls and place malicious files directly onto the system server.

How does an attacker trigger this vulnerability?

An attacker exploits this by interacting with the system's file upload module to submit a specially crafted file. Because the system lacks proper verification, it accepts the file and allows it to run, leading to code execution. The bug is not triggered by standard, legitimate administrative file uploads; it requires the submission of unauthorized or malicious files.

Is my ICS-Park system at risk if it is not on the internet?

According to Halo Surface Signal, this software is often deployed as a web-based application reachable via wide area networks for administrative convenience. While internet-facing systems are at the highest risk for remote exploitation, systems accessible within internal corporate networks may still be vulnerable if they are reachable by unauthorized users.

How should I respond to this vulnerability?

Begin by creating an inventory of all instances of the ICS-Park Smart Park Management System running in your environment. Once identified, verify which systems are accessible from external networks and confirm their business criticality. Finally, coordinate with your infrastructure team to establish ownership and initiate a remediation plan to address the software flaw.
