CVE-2025-47822 identifies a medium-severity vulnerability in Flock Safety License Plate Reader (LPR) devices running firmware versions up to 2.2. The vulnerability stems from improper access control on the on-chip debug and test interface embedded within these devices. Specifically, the debug interface, which is typically used for device testing and troubleshooting during manufacturing or maintenance, is accessible without adequate security restrictions. This flaw corresponds to CWE-1191, which involves insufficient access control mechanisms on debug or test interfaces. Exploiting this vulnerability requires network-level access (as indicated by CVSS vector AV:P), and the attack complexity is high, meaning an attacker would need specialized knowledge or conditions to exploit it. No privileges or user interaction are required, which means an unauthenticated attacker with network access could potentially leverage this flaw. The impact on confidentiality, integrity, and availability is high, suggesting that successful exploitation could lead to full compromise of the device, including unauthorized data access, manipulation, or device disruption. However, no known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved in May 2025 and published in June 2025, indicating it is a recent discovery. Given the nature of LPR devices, which collect and process sensitive vehicle and location data, this vulnerability poses a significant risk to privacy and operational security.

For European organizations, especially law enforcement agencies, municipal authorities, and private security firms utilizing Flock Safety LPR devices, this vulnerability could lead to severe consequences. Unauthorized access to the debug interface could allow attackers to extract sensitive license plate data, track vehicle movements, or manipulate device firmware to disrupt surveillance operations. This could undermine public safety initiatives, compromise investigations, and violate data protection regulations such as GDPR due to unauthorized data exposure. Additionally, attackers could potentially use compromised devices as footholds within broader network environments, leading to lateral movement and further security breaches. The high impact on confidentiality, integrity, and availability means that affected organizations could face operational downtime, reputational damage, and legal liabilities. Given the high attack complexity and requirement for network access, the threat is more pronounced in scenarios where devices are deployed in less physically secure or poorly segmented network environments.

To mitigate this vulnerability effectively, European organizations should: 1) Immediately audit all deployed Flock Safety LPR devices to identify firmware versions and isolate devices running vulnerable firmware (up to version 2.2). 2) Restrict network access to LPR devices by implementing strict network segmentation and firewall rules, allowing only trusted management systems to communicate with these devices. 3) Monitor network traffic for unusual access attempts to the debug interface ports or protocols. 4) Engage with Flock Safety to obtain firmware updates or patches as soon as they become available, and plan for prompt deployment. 5) If patches are unavailable, consider disabling or physically securing debug interfaces where possible to prevent unauthorized access. 6) Implement strong physical security controls around LPR devices to prevent local tampering. 7) Review and enhance logging and alerting mechanisms to detect potential exploitation attempts. 8) Conduct regular security assessments and penetration testing focused on IoT and embedded devices within the organization’s infrastructure to identify similar weaknesses.
