Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability arises from unsafe data handling within an ERP system, potentially allowing an unauthenticated remote attacker to execute arbitrary code. The core issue involves the system's failure to properly validate user-supplied data before processing it, creating an opening for malicious input.

Unsafe data processing in ERP systems.
Critical systems could be compromised remotely.
Confirm relevance and potential exposure of ERP systems.

Attack Path

How an attacker could exploit the issue

An attacker can reach this ERP system over the network without needing any special access or authentication. They can then send specially crafted data to a specific function within the system. If successful, this could allow the attacker to execute their own code, alter data, or otherwise misuse the system.

No authentication or prior access needed.
Specially crafted data sent to a function.
Arbitrary code execution or data manipulation.

Live Threat

Current exploitation, exposure, and threat context

An unauthenticated remote attacker could exploit this vulnerability by supplying specially crafted data to the affected ERP system's functionality. This could lead to the execution of arbitrary code, manipulation of application data, or other unintended actions.

Arbitrary code execution and data manipulation.

Operational Fix

Recommended remediation, mitigation, and detection steps

Given the vulnerability in an ERP system due to unsafe deserialization, the primary ownership likely falls to the application owners and potentially the infrastructure or platform teams responsible for managing the ERP environment. The first practical step involves identifying all instances of the ERP system, confirming their external reachability, and assessing business criticality to prioritize remediation efforts. Coordinating with the ERP vendor for any available patches or mitigation guidance is also crucial.

Application and platform owners
Verify external reachability and business criticality
Coordinate with ERP vendor for mitigation

Frequently asked questions

What is an ERP system in the context of CVE-2026-107104?

An Enterprise Resource Planning (ERP) system is a comprehensive software platform used by organizations to manage and integrate essential business processes, such as finance, supply chain, human resources, and sales, into a single unified database. Because these systems often contain sensitive company data and support critical day-to-day operations, they frequently require network-based access to allow employees, partners, and customers to interact with the system remotely.

What does unsafe deserialization mean for CVE-2026-107104?

This vulnerability is classified as CWE-502, which refers to the insecure deserialization of data. In plain terms, deserialization is the process of converting stored or transmitted data back into an object the application can use. When a system does this without sufficient validation, it can be tricked into interpreting malicious data as legitimate commands. In this case, an attacker can leverage this flaw to run unauthorized code or change data within the ERP system.

How can an attacker trigger this vulnerability?

An attacker triggers this issue by sending specially crafted data directly to the affected ERP system functionality over the network. Crucially, the system does not require the attacker to have a pre-existing account or login credentials to initiate the attack. If the application processes this malicious input without proper checks, it may execute the attacker's instructions. Standard, non-malicious data interactions that do not involve this specific deserialization function do not trigger the bug.

Why is this CVE considered relevant to my infrastructure?

Halo Surface Signal indicates that ERP systems are common targets because they are often deployed as internet-facing applications to facilitate business connectivity. If your ERP system is reachable over the internet, it is at higher risk because it is directly accessible to remote actors. Even internal instances should be evaluated, as the system's role in managing sensitive enterprise data makes it a high-value target for anyone with network access.

Is my system affected and what should I do first?

To address this, first identify all instances of the ERP software running within your environment and determine which ones are accessible over the network. Once you have a clear inventory, prioritize those that are internet-facing or manage the most critical business functions. Your immediate next step is to coordinate with your ERP software vendor to obtain and apply any available security patches, updates, or specific configuration guidance they provide to resolve this vulnerability.
