CVE-2025-8480 is a high-severity vulnerability affecting the Alpine iLX-507, specifically within its Tidal music streaming application. The root cause is an improper limitation of a pathname to a restricted directory (CWE-22), commonly known as a path traversal vulnerability. This flaw allows network-adjacent attackers to supply crafted input that is not properly validated before being used in a system call, enabling arbitrary command injection and remote code execution on the device. Notably, exploitation does not require authentication, significantly lowering the barrier for attackers. The vulnerability impacts version 6.0.000 of the Alpine iLX-507. The CVSS v3.0 score is 8.0, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. Although no known exploits are currently observed in the wild, the potential for remote code execution without authentication makes this a critical risk for affected devices. The Alpine iLX-507 is an in-vehicle multimedia receiver, often integrated into automotive infotainment systems, which means exploitation could compromise vehicle systems or user data. The vulnerability was cataloged by the Zero Day Initiative (ZDI) as ZDI-CAN-26357 and published on August 1, 2025. No patches have been released at the time of this report, increasing urgency for mitigation.

For European organizations, the impact of CVE-2025-8480 is significant, especially for those in the automotive sector, fleet management, or companies providing connected vehicle services. Compromise of Alpine iLX-507 devices could lead to unauthorized access to vehicle infotainment systems, potentially exposing sensitive user data such as location, contacts, and media usage. More critically, remote code execution could serve as a foothold for lateral movement within vehicle networks, risking broader vehicle control or disruption. This could affect passenger safety and privacy, as well as corporate liability and regulatory compliance under GDPR and automotive cybersecurity standards like UNECE WP.29. The lack of authentication requirement means attackers could exploit this vulnerability remotely over local networks or possibly via compromised mobile devices connected to the infotainment system. Disruption or manipulation of vehicle systems could result in operational downtime, reputational damage, and financial loss for European automotive manufacturers, suppliers, and service providers.

Given the absence of an official patch, European organizations should implement immediate compensating controls. First, restrict network access to Alpine iLX-507 devices by segmenting vehicle infotainment systems from critical enterprise networks and limiting connectivity to trusted sources only. Employ network monitoring to detect anomalous traffic patterns indicative of exploitation attempts targeting the Tidal application or suspicious system calls. Disable or restrict the use of the Tidal music streaming application on affected devices where feasible. Engage with Alpine and authorized dealers to obtain firmware updates or advisories as soon as they become available. Additionally, implement strict input validation and filtering at any integration points that interact with the infotainment system, if customization is possible. For fleet operators, enforce policies to update or replace vulnerable devices promptly and educate users on minimizing exposure to untrusted networks or devices. Finally, maintain incident response readiness to quickly isolate and remediate compromised devices.
