Flock Safety Android Keystore Hardcoded Private Key Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2025-59407

The vulnerability involves a hardcoded keystore and password within an Android application running on specialized physical hardware, specifically License Plate Readers and edge compute devices. These devices typically operate within managed private networks or dedicated infrastructure rather than being exposed directly to the public internet, making general public exposure unlikely.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory highlights a critical vulnerability found in the Flock Safety DetectionProcessing Android application. The issue stems from the application bundling a Java Keystore with a hardcoded password directly within its code, which includes a private key. While the specific devices and network configurations involved may limit broad impact, the presence of this credential could, in certain scenarios, allow for unauthorized access and control of the affected devices, potentially compromising the integrity of the data they process.

Hardcoded credentials in the app pose a risk.
Confirms relevance and exposure on specialized devices.
Assess impact based on device deployment and network security.

Attack Path

How an attacker could exploit the issue

An attacker could potentially gain access to sensitive information or a private key by analyzing the Flock Safety DetectionProcessing Android application. This application is installed on various Flock Safety devices, including license plate readers and edge compute devices. The vulnerability lies in the application bundling a Java Keystore with its hardcoded password directly within its code, exposing a private key that could be used for further malicious activities.

No authentication required for access.
Application code analysis to find credentials.
Exposure of sensitive private key.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could expose sensitive information stored within a hardcoded Java Keystore, which is bundled with the Flock Safety DetectionProcessing application on specific devices. When supported by the advisory, this could lead to unauthorized access to a private key.

Private key and sensitive data at risk.
Information disclosure when application is analyzed.
Compromise of system integrity and confidentiality.

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability impacts Flock Safety License Plate Readers and Bravo Edge AI Compute Devices, suggesting that application owners, platform teams, and potentially vendor management are responsible for remediation. The immediate first step is to identify all deployed instances, assess their network exposure and business criticality, and then locate the accountable owner to plan a risk-based remediation strategy.

Ownership: Flock Safety application owners.
Verify first: Device network exposure and criticality.
Action: Plan risk-based remediation.

Frequently asked questions

What is the Flock Safety DetectionProcessing application?

It is an Android-based software component used to manage data and operations on physical hardware, specifically Falcon and Sparrow License Plate Readers and Bravo Edge AI Compute Devices. These tools are designed to monitor and process vehicle data for security and analytics purposes.

How does CVE-2025-59407 represent a weakness in software security?

This vulnerability is classified as CWE-321: Use of Hard-coded Cryptographic Key. It means the software includes a secret digital key and its password directly inside the application's code. Because these credentials are fixed, they cannot be changed by users, creating a permanent security flaw where the key is vulnerable to extraction by anyone who accesses the app files.

Is this vulnerability triggered by simple interactions with the device?

No. The vulnerability is not triggered by typical daily operation or normal user commands. Instead, it requires an attacker to extract and analyze the application's internal code to locate the bundled keystore and its hardcoded password.

How relevant is this CVE for my environment according to Halo Surface Signal?

Halo Surface Signal labels this as Unlikely to be broadly exposed. Because the vulnerability is tied to specialized physical hardware like license plate readers, these devices are usually deployed in managed private networks or dedicated infrastructure rather than being directly reachable from the public internet.

What are the first steps to take if I manage these devices?

Start by identifying all instances of the affected hardware in your inventory. Review how these devices are connected to your network to determine if they are isolated or have wider access. Finally, coordinate with your technical team or vendor point of contact to establish a remediation plan based on the criticality of the data the devices handle.
