CVE-2025-9383 is a security vulnerability identified in the FNKvision Y215 CCTV Camera, specifically affecting version 10.194.120.40. The vulnerability arises from the use of a weak cryptographic hash function in the handling of the /etc/passwd file, which is a critical system file responsible for storing user account information on Unix-like systems. The weakness in the hash function compromises the integrity of password storage, potentially allowing an attacker with local access to the device to exploit this flaw. However, the attack complexity is high, requiring local environment access and significant effort to exploit, and no user interaction is needed. The vulnerability does not affect confidentiality or availability directly but impacts the integrity of authentication credentials. The vendor, FNKvision, was notified early but has not responded or provided a patch, and no known exploits are currently active in the wild. The CVSS 4.0 score is low (2.0), reflecting the limited scope and difficulty of exploitation. This vulnerability is primarily a local privilege escalation risk due to weak password hashing, which could facilitate further compromise if an attacker gains initial access to the device.

For European organizations deploying FNKvision Y215 CCTV cameras, this vulnerability poses a limited but non-negligible risk. Since the exploit requires local access and is difficult to execute, remote attackers cannot directly leverage this vulnerability without first breaching perimeter defenses. However, if an attacker gains physical or network-level local access (e.g., via compromised internal networks or insider threats), they could exploit the weak hash to escalate privileges or extract password hashes for offline cracking. This could lead to unauthorized control over the CCTV device, potentially allowing attackers to manipulate video feeds, disable surveillance, or use the device as a foothold for lateral movement within the network. Given the critical role of CCTV in physical security, any compromise could undermine organizational security posture. The lack of vendor response and patch availability increases the risk of future exploitation as attackers may develop exploits over time. Organizations in Europe with deployments of this specific camera model should be aware of the vulnerability's limitations but also its potential to facilitate deeper network compromise if combined with other attack vectors.

To mitigate this vulnerability, European organizations should first inventory their CCTV devices to identify any FNKvision Y215 cameras running the affected firmware version 10.194.120.40. Since no patch is currently available, organizations should implement strict network segmentation to isolate these devices from critical network segments, limiting local access only to trusted administrators. Physical security controls should be enhanced to prevent unauthorized local access to the devices. Monitoring and logging of access to CCTV devices should be increased to detect any suspicious activity. Organizations should consider disabling unnecessary services or interfaces on the cameras to reduce attack surface. If possible, replacing affected devices with models from vendors that provide timely security updates is advisable. Additionally, organizations should enforce strong internal access controls and multi-factor authentication for administrative access to CCTV management systems to reduce the risk of privilege escalation. Regular security assessments and penetration testing focusing on physical and network access to CCTV infrastructure can help identify and remediate potential attack paths.
