CVE-2025-47822 identifies a vulnerability in Flock Safety License Plate Reader (LPR) devices, specifically those running firmware versions up to 2.2. The issue stems from an on-chip debug and test interface that suffers from improper access control, classified under CWE-1191. This weakness allows unauthorized parties to potentially access the debug interface, which is typically intended for internal testing and development purposes. Exploiting this vulnerability could enable attackers to gain high levels of control over the device, including the ability to read or modify sensitive data, alter device firmware, or disrupt normal operations. The vulnerability has a CVSS 3.1 base score of 6.4, indicating a medium severity level. The vector details show that the attack requires physical access (AV:P - Physical), has high attack complexity (AC:H), requires no privileges (PR:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), meaning that successful exploitation could lead to full compromise of the device's data and functionality. No known exploits are currently reported in the wild, and no patches have been linked yet, suggesting that mitigation may rely on firmware updates or physical security controls. The vulnerability is significant because LPR devices are often deployed in public or semi-public environments for law enforcement and security monitoring, making them attractive targets for attackers seeking to manipulate surveillance data or disrupt security operations.

For European organizations, especially law enforcement agencies, municipalities, and private security firms using Flock Safety LPR devices, this vulnerability poses a substantial risk. Unauthorized access to the debug interface could allow attackers to tamper with license plate data, potentially enabling evasion of surveillance or framing innocent parties. The high impact on confidentiality, integrity, and availability means that attackers could extract sensitive data, inject false data, or disable the devices entirely, undermining public safety and trust. Given the physical access requirement, the threat is more pronounced in locations where devices are accessible or insufficiently protected. The disruption or manipulation of LPR systems could also affect traffic management and criminal investigations, leading to broader societal impacts. Additionally, compromised devices could be leveraged as entry points into wider network infrastructures if connected, increasing the risk of lateral movement and further breaches within European organizations.

Mitigation should focus on both immediate and long-term measures. Firstly, organizations should enforce strict physical security controls around LPR devices to prevent unauthorized physical access, including secure mounting, tamper-evident seals, and surveillance of device locations. Secondly, Flock Safety should be engaged to provide firmware updates or patches that properly restrict access to the on-chip debug interface. Until patches are available, disabling or restricting debug interfaces where possible is advisable. Network segmentation should be implemented to isolate LPR devices from critical infrastructure, limiting potential lateral movement if a device is compromised. Regular audits and inspections of device integrity and configuration can help detect tampering attempts early. Additionally, organizations should monitor for anomalous device behavior or unexpected data patterns that could indicate exploitation. Finally, updating incident response plans to include scenarios involving LPR device compromise will improve preparedness.
