CVE-2025-2355 in App
Summary
by MITRE • 03/17/2025
A vulnerability was found in BlackVue App 3.65 on Android and classified as problematic. Affected by this issue is some unknown functionality of the component API Endpoint Handler. The manipulation of the argument BCS_TOKEN/SECRET_KEY leads to unprotected storage of credentials. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

This vulnerability resides within the BlackVue App version 3.65 for Android platforms and represents a critical security flaw in the application's API endpoint handler component. The issue stems from improper handling of authentication tokens and secret keys during the application's credential management process. Specifically, when the application processes the BCS_TOKEN and SECRET_KEY arguments, it fails to implement adequate cryptographic protection mechanisms for storing these sensitive credentials within the device's local storage. This weakness creates a persistent security risk where authentication information remains accessible to unauthorized parties who can gain local access to the device. The vulnerability classification as "problematic" indicates that the flaw has been identified and validated by security researchers, with the exploitation techniques already made public and available for malicious actors to leverage.
The technical implementation flaw manifests in the application's insecure data storage practices where the BCS_TOKEN and SECRET_KEY values are written to local storage without proper encryption or access controls. This represents a direct violation of security best practices and aligns with CWE-312 (Cleartext Storage of Sensitive Information) and CWE-522 (Insufficiently Protected Credentials) categories. The attack vector requires local access to the device, meaning that an attacker must already have physical or remote access to the target Android device to exploit this vulnerability. This local privilege escalation requirement does not diminish the severity of the issue, as it still allows for unauthorized access to the application's protected resources and potentially enables further compromise of the device or associated systems. The fact that the exploit has been publicly disclosed and is available for use indicates that threat actors have already developed working methods to leverage this weakness.
The operational impact of this vulnerability extends beyond simple credential theft, as the compromised BCS_TOKEN and SECRET_KEY could provide attackers with unauthorized access to BlackVue's backend services and potentially to connected devices or data streams. This weakness enables persistent access to surveillance footage, device management functions, and other sensitive information that users expect to remain protected. The vulnerability affects the application's API endpoint handler component, which likely manages communication between the mobile application and BlackVue's servers, making it a critical point of failure in the application's security architecture. Attackers could potentially use these stolen credentials to access other users' accounts, manipulate device configurations, or gain access to proprietary surveillance data, leading to privacy violations and potential security breaches.
Security mitigations for this vulnerability should focus on implementing proper encryption for all sensitive data stored locally on the device. The application should utilize Android's Keystore system or similar platform-specific secure storage mechanisms to protect authentication tokens and secret keys. Additionally, the API endpoint handler component must be redesigned to avoid storing sensitive credentials in plaintext format, implementing proper cryptographic protection for all stored data. The application should also implement secure credential rotation mechanisms and validate the integrity of stored credentials during application startup. Organizations should also consider implementing additional access controls and monitoring for suspicious activities that could indicate credential compromise. The vendor's lack of response to early disclosure attempts represents a significant gap in responsible disclosure practices and highlights the importance of proactive security measures and vendor accountability in maintaining application security. This vulnerability demonstrates the critical need for regular security assessments and proper incident response procedures to address security flaws before they can be exploited by malicious actors.
