Overview
CVE-2025-64304 describes a security vulnerability discovered in the FOD (Fuji On Demand) application. This vulnerability stems from the use of hard-coded cryptographic keys within the application. An unauthenticated attacker with local access to the application can potentially retrieve these cryptographic keys, leading to further exploitation.
Technical Details
The FOD application, developed by Fujitv, utilizes cryptographic keys for security purposes. However, instead of employing a secure key management system, these keys are embedded directly within the application’s code. This hardcoding makes them accessible to anyone with the ability to analyze the application’s binaries or memory. A local attacker without authentication can extract the hardcoded keys.
CVSS Analysis
Currently, the CVSS score for CVE-2025-64304 is listed as N/A, indicating that a formal severity assessment has not yet been conducted or is not available at the time of this writing. However, based on the nature of the vulnerability, the potential impact could be significant, warranting a thorough evaluation once a CVSS score is assigned. If we were to estimate, given that local access is required, it would likely be a Medium severity vulnerability if exploited.
Possible Impact
The retrieval of hardcoded cryptographic keys can have several severe consequences:
- Data Decryption: The keys could be used to decrypt sensitive data stored by the application, potentially exposing user information, viewing history, or other proprietary content.
- Account Compromise: Depending on how the keys are used, an attacker might be able to forge authentication tokens or gain unauthorized access to user accounts.
- Privilege Escalation: The keys may grant elevated privileges within the application or on the underlying system.
- Code Tampering: Keys may be used to digitally sign code, allowing an attacker to introduce malicious code that appears legitimate.
Mitigation and Patch Steps
To address CVE-2025-64304, the following mitigation steps are recommended:
- Apply the Update: Fujitv has likely released a patched version of the FOD application that replaces the hardcoded keys with a more secure key management system. Users should update to the latest version immediately.
- Key Rotation: If a patch is not immediately available, consider contacting Fujitv support to request a temporary key rotation strategy if possible. However, hardcoded keys are fundamentally flawed and should be replaced by a more secure solution.
- Monitor for Suspicious Activity: Implement monitoring mechanisms to detect any unusual activity related to the FOD application, such as unauthorized access attempts or data exfiltration.
