Neye3C Firmware Update Access Control Information Disclosure.

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2024-48538

The vulnerability exists within the firmware update and download processes of a mobile application (APK file) and involves static analysis of code and data. This is a local client-side issue related to development or reverse engineering of an application package, rather than a network-reachable service or internet-facing infrastructure component.

Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in the firmware update process of the Neye3C mobile application, allowing unauthorized access to sensitive information. While the direct business impact is currently assessed as very unlikely due to the technical nature of the exploit, confirming relevance and exposure is recommended.

Sensitive data exposed through firmware updates.
Low likelihood of business impact.
Verify if this affects your environment.

Attack Path

How an attacker could exploit the issue

An attacker could potentially gain unauthorized access to sensitive information by examining the code and data contained within the Neye3C application's APK file. This is made possible by weaknesses in how the firmware update and download processes handle access control. By analyzing the application's package, an attacker may uncover sensitive details.

Operational Fix

Recommended remediation, mitigation, and detection steps

Given that the vulnerability is within a mobile application's firmware update process, the initial step is to identify all instances of the affected application across your mobile device fleet. This requires coordination between mobile device management (MDM) administrators and application owners to confirm the presence of the application, assess its reachability, and determine its criticality to business operations. Once identified, the accountable owner should be contacted to plan a targeted remediation strategy, which may involve coordinating with the vendor for a secure firmware update or exploring temporary risk-reduction measures if immediate patching is not feasible.

Application owners should lead the issue.
Verify all affected devices are inventoried.
Plan vendor-coordinated updates.

Frequently asked questions

What is the Neye3C application?

Neye3C is a mobile application used to interact with and manage security camera or DVR systems. It handles critical tasks like firmware updates and data downloads for these devices, serving as the bridge between a user's mobile device and the hardware's operating code.

What does CVE-2024-48538 mean for software security?

This vulnerability is classified as CWE-862, or Missing Authorization. It means the application fails to properly restrict access to its internal processes. In this specific case, the flaw allows unauthorized parties to bypass controls and inspect sensitive information embedded within the application's code and data files.

How can an attacker trigger this vulnerability?

An attacker must gain access to the application's APK file to perform static analysis on its contents. This bug is not triggered by simply using the app's standard network features; it requires an actor to extract and examine the package's underlying code and data structures to uncover the exposed information.

Is my environment at risk according to Halo Surface Signal?

Halo Surface Signal indicates that a business-level impact is very unlikely. Because this issue is a client-side vulnerability located within the APK file itself—rather than an active, internet-facing service or infrastructure component—it does not present the typical risks associated with network-based attacks.

Do I need to take action to secure my devices?

Yes, you should begin by inventorying where Neye3C is installed across your mobile device fleet. Collaborate with your mobile management team to confirm which devices use this app, then coordinate with the application owner to track vendor-provided updates or consider risk-reduction measures if an update is not immediately available.
