CVE-2025-8915 is a vulnerability identified in the Kiloview N30 device firmware version 2.02.246, categorized under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The core issue is the presence of a hardcoded TLS private key and certificate embedded within the device firmware. This design flaw allows an attacker with network access to perform a man-in-the-middle (MitM) attack by impersonating the device or intercepting encrypted communications. The vulnerability does not require any privileges or authentication to exploit, but user interaction is necessary, such as connecting to the device's network or initiating communication with it. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:P), and high impact on confidentiality, integrity, and availability (VC:H, VI:H, VA:H). The scope is limited (SC:L), with low impact on security requirements (SI:L, SA:L). Although no public exploits are reported yet, the presence of hardcoded cryptographic material is a critical security lapse that can lead to interception and manipulation of sensitive data streams. This vulnerability primarily affects organizations relying on Kiloview N30 devices for secure video transmission or other networked media applications.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive communications, particularly in sectors such as broadcasting, media production, and secure video conferencing where Kiloview N30 devices are deployed. An attacker exploiting this flaw can intercept, decrypt, and potentially alter data transmitted over the network, leading to data breaches, espionage, or disruption of services. The exposure of TLS private keys undermines the trust model of encrypted communications, making it easier for adversaries to conduct persistent surveillance or inject malicious content. This can result in reputational damage, regulatory penalties under GDPR for data exposure, and operational disruptions. The vulnerability's ease of exploitation without authentication increases the attack surface, especially in environments with insufficient network segmentation or monitoring. European critical infrastructure relying on secure video feeds may face heightened risks, impacting national security and business continuity.

1. Immediate action should focus on obtaining and applying any official firmware updates or patches from Kiloview once released to remove hardcoded keys and certificates. 2. Until patches are available, isolate Kiloview N30 devices on segmented, trusted networks with strict access controls to limit exposure. 3. Disable any unnecessary network services and interfaces on the device to reduce attack vectors. 4. Implement network monitoring and intrusion detection systems to identify anomalous traffic indicative of MitM attacks or unauthorized access attempts. 5. Replace hardcoded certificates with unique, securely generated certificates per device, managed through a robust PKI infrastructure. 6. Educate users and administrators about the risks of connecting to untrusted networks and the importance of verifying device authenticity. 7. Conduct regular security audits and penetration testing focusing on networked media devices to proactively identify similar vulnerabilities. 8. Consider deploying additional encryption layers or VPN tunnels for sensitive communications as a compensating control.
