Horizon Alert

Summary of the vulnerability and why it matters

An unauthenticated remote code execution vulnerability has been identified in the fastmag_sync component of Home-Made.io. This flaw allows an attacker to execute arbitrary code, which could have significant implications for affected systems. The main concern at this time is to confirm if this specific technology is in use and assess the potential exposure.

Remote attackers can run unauthorized code.
Confirm relevance and exposure; potential for high impact.
Understand technology use and assess organizational risk.

Attack Path

How an attacker could exploit the issue

An attacker can remotely target the `getPhpBin()` component in Home-Made.io fastmagsync, which is exposed via a web interface. Without needing any prior access or interaction, an attacker could leverage this vulnerability to execute arbitrary code. This could potentially allow them to compromise the integrity and availability of the affected system.

No special access needed.
Triggered via web request.
Remote code execution risk.

Live Threat

Current exploitation, exposure, and threat context

The `fastmagsync` component in Home-Made.io for PrestaShop could allow a remote attacker to execute arbitrary code. This could occur when the `getPhpBin()` function is reachable over the network and the attacker can manipulate its input. When supported, this could lead to the execution of unauthorized commands on the affected server.

System code execution.
Code execution via network requests.
Compromised server.

Operational Fix

Recommended remediation, mitigation, and detection steps

Application owners and platform teams are likely responsible for addressing this vulnerability in the fastmagsync module. The first practical step is to identify all instances of this module within your PrestaShop environment, confirm its exposure to the internet, and determine if it's business-critical. Once identified, work with the accountable owner to plan and execute remediation based on the assessed risk, potentially involving vendor coordination or temporary mitigation strategies if immediate patching is not feasible.

Application owners should own the issue.
Verify internet reachability and business criticality.
Plan remediation based on assessed risk.

Frequently asked questions

What is Home-Made.io fastmagsync?

Fastmagsync is a software module designed for the PrestaShop e-commerce platform. It is typically used to integrate online stores with external services, synchronizing data between the web shop and business management tools. Because it functions as an extension to an e-commerce framework, it sits within the web server environment to handle data transfers and backend communications.

What does CVE-2024-28386 mean for my system?

This vulnerability is classified as CWE-94, or Improper Control of Generation of Code. In plain terms, the software fails to properly sanitize input before processing it. Because of this weakness, an attacker can send a specially crafted request to the system, tricking it into executing unauthorized commands or code as if they were legitimate instructions from the application itself.

How is this vulnerability triggered?

An attacker triggers this flaw by targeting the getPhpBin() component via a web request. The issue occurs when this function receives manipulated input from an external source. It is important to note that the vulnerability does not require the attacker to have a pre-existing account, special privileges, or any form of interaction from a legitimate user to initiate the malicious code execution.

Is my server at risk if it uses this module?

According to Halo Surface Signal, this software is a module for an e-commerce platform, which is almost always deployed in a public-facing environment to handle customer traffic. Because the component is reachable over the network and does not require authentication, any instance of fastmagsync exposed to the internet is a potential target for remote code execution.

What should I do if I run fastmagsync?

Your first step is to locate all instances of the fastmagsync module within your PrestaShop environment. Once you have identified them, evaluate whether the module is business-critical and check if it is reachable from the public internet. Coordinate with your application owners to prioritize this, planning for a patch or update from the vendor while assessing your risk level.
