DreamMaker Arbitrary File Upload Leads to Server Code Execution.

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-10071

The vulnerability allows unauthenticated remote attackers to upload and execute files on the server. Because it requires no authentication and enables arbitrary code execution, this type of flaw in a web application is typically found in public-facing endpoints designed for user interaction or file processing, making it very likely to be reachable from the public internet.

Horizon Alert

Summary of the vulnerability and why it matters

A security vulnerability has been identified in DreamMaker software, a product developed by Interinfo. This issue allows unauthorized remote attackers to upload and execute malicious files, potentially leading to compromised server operations. The primary concern is to confirm if this software is in use and exposed to potential threats.

  • Unauthenticated attackers can upload malicious code.
  • This could impact server integrity and operations.
  • Verify relevance and potential exposure within the organization.

Attack Path

How an attacker could exploit the issue

An unauthenticated remote attacker can leverage the Arbitrary File Upload vulnerability in DreamMaker to upload and execute malicious files, such as web shell backdoors, on the server. This grants the attacker the ability to run arbitrary code, potentially leading to a complete compromise of the server.

  • No authentication required.
  • Upload and execute arbitrary files.
  • Arbitrary code execution on server.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow unauthenticated remote attackers to upload and run malicious code on the server when exposed to the internet. This could lead to unauthorized control of the server and compromise its operations.

  • Server-side code execution.
  • Unauthenticated remote file upload.
  • Complete server compromise.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Interinfo DreamMaker product's arbitrary file upload vulnerability requires immediate attention from teams responsible for application security and platform management. The first practical step is to identify all instances of DreamMaker within the environment, assess their exposure to the network, and confirm ownership to prioritize remediation. This process ensures that critical assets are protected and that the appropriate teams are engaged for effective resolution.

  • Application owners and platform teams should lead the effort.
  • Verify DreamMaker instances and their network exposure.
  • Plan remediation or vendor coordination.

Frequently asked questions

What is DreamMaker by Interinfo?

DreamMaker is a software application developed by Interinfo, typically used for tasks that involve file processing or user interaction within a web environment. Because it handles incoming files, the application includes features designed to accept and manage uploads from users, which serves as the functional context for this vulnerability.

How does the arbitrary file upload vulnerability work in CVE-2026-10071?

This vulnerability, classified as CWE-434, happens when a system does not properly restrict the types of files uploaded to it. In the context of CVE-2026-10071, the software allows a remote attacker to upload malicious files, such as web shells. Once saved to the server, these files can be executed by the attacker to run arbitrary code, bypassing intended system security.

Does a user need to be logged in to trigger this vulnerability?

No, authentication is not required to exploit this flaw. An attacker can reach the vulnerable file upload function without needing valid credentials or an existing session. It is important to note that the vulnerability relies on the application accepting these files; it is not triggered by standard web browsing or routine site interactions that do not utilize the upload capability.

Why is this CVE considered high risk based on Halo Surface Signal?

Halo Surface Signal indicates that this vulnerability is very likely to be reachable from the public internet. Because the flaw allows unauthenticated attackers to execute code via public-facing endpoints, any instance of DreamMaker accessible online poses a significant risk of compromise. Internal-only instances still require attention, but internet-facing assets are the most immediate priority.

What are the first steps to take if I run DreamMaker?

Begin by auditing your environment to locate all active instances of the Interinfo DreamMaker software. Once identified, evaluate whether these instances are exposed to the network and determine who owns the deployment. Engaging the relevant application security and platform management teams is essential to coordinate the next steps for protecting your assets and preparing for remediation.
