CVE-2025-47819 is a medium-severity vulnerability affecting Flock Safety Gunshot Detection devices prior to version 1.3. The vulnerability is categorized under CWE-1191, which relates to improper access control on on-chip debug and test interfaces. These devices incorporate an on-chip debug interface intended for development and testing purposes. However, in affected versions, this interface lacks adequate access control mechanisms, potentially allowing unauthorized parties to interact directly with the device's internal components. Exploiting this vulnerability requires physical proximity or network access with high attack complexity (as indicated by the CVSS vector AV:P/AC:H), and no privileges or user interaction are required. Successful exploitation could lead to complete compromise of confidentiality, integrity, and availability of the device, as attackers could extract sensitive data, manipulate device behavior, or disable the gunshot detection functionality. The vulnerability does not currently have known exploits in the wild, but the potential impact is significant given the critical role these devices play in public safety and law enforcement environments. The CVSS score of 6.4 reflects a medium severity level, balancing the high impact with the difficulty of exploitation and limited attack vector.

For European organizations, especially law enforcement agencies, municipalities, and private security firms relying on Flock Safety Gunshot Detection devices, this vulnerability poses a tangible risk. Compromise of these devices could lead to unauthorized disclosure of sensitive audio or event data, manipulation or suppression of gunshot detection alerts, and disruption of public safety monitoring systems. This could undermine trust in security infrastructure, delay emergency response, and potentially endanger public safety. Given the critical nature of gunshot detection in urban security and crime prevention, exploitation could have cascading effects on community safety and law enforcement effectiveness. Furthermore, organizations may face regulatory and compliance challenges under European data protection laws if sensitive data is exposed or mishandled due to this vulnerability.

To mitigate this vulnerability, European organizations should prioritize upgrading all affected Flock Safety Gunshot Detection devices to version 1.3 or later, where the access control issue on the on-chip debug interface is resolved. Until upgrades are applied, physical security controls should be enhanced to restrict unauthorized physical access to the devices, as exploitation requires proximity or direct access. Network segmentation and strict firewall rules should be implemented to limit access to device management interfaces. Organizations should also conduct regular audits and monitoring for unusual device behavior or unauthorized access attempts. If possible, disabling or restricting debug interfaces through device configuration should be considered as a temporary measure. Additionally, organizations should engage with Flock Safety for any available patches or security advisories and incorporate this vulnerability into their risk management and incident response planning.
