CVE-2025-8473 is an OS command injection vulnerability identified in the Alpine iLX-507 device, specifically within the UPDM_wstpCBCUpdStart function. This vulnerability arises due to improper neutralization of special elements in user-supplied input before it is used in a system call, classified under CWE-78. An attacker with physical access to the device can exploit this flaw without requiring authentication, enabling them to execute arbitrary code with root privileges. The vulnerability affects version 6.0.000 of the Alpine iLX-507. The CVSS v3.0 score is 6.4, indicating a medium severity level, with vector metrics showing that exploitation requires physical access (AV:P), low attack complexity (AC:L), low privileges (PR:L), and user interaction (UI:R). The impact on confidentiality, integrity, and availability is high, as successful exploitation allows full control over the device. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was assigned and published by the Zero Day Initiative (ZDI) under identifier ZDI-CAN-26317. Given the nature of the device (Alpine iLX-507 is an in-car multimedia receiver), the attack vector is limited to scenarios where an attacker can physically interact with the device, such as in vehicles or environments where the device is installed. The root-level code execution could allow attackers to manipulate device functions, potentially affecting vehicle infotainment systems or connected components, raising concerns about privacy and safety depending on integration with vehicle systems.

For European organizations, the impact of this vulnerability depends largely on the deployment context of Alpine iLX-507 devices. Organizations in automotive, fleet management, or transportation sectors using these devices could face risks of unauthorized code execution leading to data breaches, disruption of infotainment services, or potential escalation to vehicle control systems if integrated. The physical access requirement limits remote exploitation but insider threats or physical tampering in parking lots, service centers, or during transport could be vectors. Confidentiality is at risk due to potential access to stored data or communications. Integrity and availability could be compromised by malicious code altering device behavior or causing denial of service. The lack of authentication for exploitation increases risk in environments with less physical security. Additionally, the root-level access could facilitate persistence and lateral movement if the device is network-connected. The vulnerability could also affect compliance with European data protection regulations if personal data is exposed or manipulated.

Given the absence of a patch, European organizations should implement strict physical security controls to prevent unauthorized access to Alpine iLX-507 devices, including secure storage and monitoring of vehicles or equipment containing these devices. Disable or restrict physical interfaces where possible to limit attacker interaction. Network segmentation should be enforced to isolate these devices from critical systems, reducing the risk of lateral movement. Monitoring for unusual device behavior or system calls may help detect exploitation attempts. Organizations should engage with Alpine for timely patch releases and apply updates promptly once available. Additionally, consider deploying endpoint detection and response (EDR) solutions capable of identifying anomalous root-level commands on these devices. For fleet operators, incorporate device integrity checks during routine maintenance. Finally, educate personnel on the risks of physical tampering and enforce strict access policies.
