im3x Scriptables Arbitrary Command Injection via Crafted Filename

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-38595

The vulnerability exists in a web application endpoint (/sync) that accepts file uploads. As a web-based service endpoint, this component is commonly exposed to the internet or wide internal networks to facilitate functionality, making it a likely target for external reachability in typical web application deployment patterns.

Horizon Alert

Summary of the vulnerability and why it matters

An unauthorized individual could potentially execute commands on the server by uploading a specially named file. This vulnerability affects a web application feature that allows file uploads. The primary concern is to confirm if this specific technology is in use and if it is accessible in a way that could be exploited.

Uploaded files can run system commands.
It allows remote code execution without authentication.
Verify if this scriptable technology is deployed.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by uploading a specially crafted file through the `/sync` endpoint. This action allows for the injection of operating system commands, which could lead to the execution of arbitrary code on the server.

Attacker uploads a crafted file.
File upload to `/sync` endpoint triggers vulnerability.
Arbitrary command execution on server.

Live Threat

Current exploitation, exposure, and threat context

When supported by the advisory, an attacker could inject arbitrary operating system commands by uploading a specially named file to the `/sync` endpoint. This could affect the availability and integrity of the affected system.

System commands.
Malicious file upload.
System compromise.

Operational Fix

Recommended remediation, mitigation, and detection steps

To address this command injection vulnerability, the platform or application team responsible for the im3x Scriptables deployment should take the lead. The first practical step is to identify all instances of the affected technology, confirm their accessibility and business criticality, and then determine the accountable owner for remediation planning based on the assessed risk.

Identify accountable platform/application owners.
Verify external reachability and criticality.
Plan remediation based on risk.

Frequently asked questions

What is im3x Scriptables?

im3x Scriptables is a software framework used to handle automated tasks and scripting within a web-based environment. It typically functions as a backend component that processes data, including file transfers, to support application logic.

What does CVE-2026-38595 mean?

This CVE describes a critical vulnerability involving OS Command Injection (CWE-78) and Path Traversal (CWE-22). It means the application fails to safely handle filenames during a file upload process, allowing an attacker to insert malicious commands that the server runs with its own system privileges.

How is this command injection triggered?

The vulnerability is triggered by sending a request to the /sync endpoint with a file containing a specially crafted name. Simply navigating to the site or viewing files without performing an upload action does not trigger the execution of these commands.

Is my system reachable by attackers?

Halo Surface Signal indicates this vulnerability is likely reachable if your instance of im3x Scriptables is connected to the internet or a broad internal network. Because the /sync endpoint is designed to accept file uploads, it is often exposed, increasing the likelihood that it could be targeted by an external actor.

What should I do if I use im3x Scriptables?

Your first step is to locate every instance of im3x Scriptables running in your environment. Once identified, evaluate whether the /sync endpoint is accessible to unauthorized users and determine which team is responsible for managing the application to coordinate a security review.
