Horizon Alert

Summary of the vulnerability and why it matters

This critical vulnerability affects the Restaurant Brands International assistant platform, which handles drive-thru and ordering systems. It involves a weakness in how the system authenticates users, potentially allowing unauthorized access to sensitive functions. The primary concern is to determine if our organization utilizes this specific platform and, if so, to understand its potential exposure.

Weak authentication on restaurant ordering systems.
Critical flaw could impact customer-facing operations.
Confirm relevance and assess any potential exposure.

Attack Path

How an attacker could exploit the issue

An attacker could potentially gain unauthorized access to the RBI assistant platform's diagnostic screen. This is possible because the platform relies on client-side authentication, meaning the security checks happen on the user's device rather than on the server. If an attacker can bypass or circumvent this client-side authentication, they could access sensitive diagnostic information.

Accessible over the network without authentication.
Diagnostic screen accessed via flawed authentication.
Unauthorized access to sensitive data and controls.

Live Threat

Current exploitation, exposure, and threat context

The Restaurant Brands International (RBI) assistant platform, when relying on client-side authentication for its diagnostic screen, could expose sensitive system information or allow unauthorized modifications to service behavior. This could occur when the diagnostic screen is accessible and its authentication mechanisms are bypassed.

Bypassing weak client-side authentication.
Unauthorized system access or modification.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Restaurant Brands International (RBI) assistant platform's reliance on client-side authentication for its diagnostic screen likely requires attention from application owners and potentially infrastructure or security teams, depending on deployment. The immediate practical step is to identify all instances of this platform, confirm their internet reachability and business criticality, and then coordinate with the platform's accountable owner to prioritize remediation or implement compensating controls.

Frequently asked questions

What is the Restaurant Brands International assistant platform?

This software serves as a central management and interface layer for automated systems found in restaurant environments, such as drive-thru and digital ordering kiosks. It acts as a gateway to coordinate operations and monitor performance across various physical restaurant locations.

How does CVE-2025-62650 allow unauthorized access?

This vulnerability is classified as CWE-603, which involves the use of client-side authentication. In this case, the platform improperly trusts the user's device to verify identity instead of performing that check on the secure server. By manipulating the client-side code, an attacker can bypass these checks and interact with restricted diagnostic screens.

Do I need special access to trigger this vulnerability?

No special access or prior credentials are required. Because the system relies on the client device for security, an attacker can simply bypass those local checks to gain unauthorized entry. Simply interacting with the platform over the network is sufficient; the bug does not require an attacker to have a legitimate account or administrative privileges.

Why is CVE-2025-62650 a concern for my network?

According to Halo Surface Signal, this platform is often deployed as an internet-connected gateway to facilitate operations. This configuration frequently leaves these systems reachable from the public internet, meaning they do not necessarily need to be internal or behind a corporate firewall to be accessed by unauthorized parties.

How should I respond to this threat?

Begin by auditing your environment to locate every instance of the RBI assistant platform. Once identified, evaluate whether these instances are accessible from the internet and verify their business criticality. Engage with the platform owners immediately to prioritize system updates or the implementation of compensating network controls to restrict access.
