CVE-2025-59402 is a medium-severity vulnerability affecting the Flock Safety Bravo Edge AI Compute Device, specifically the BRAVO_00.00_local_20241017 firmware version. The device accepts the default Thundercomm TurboX 6490 Firehose loader in Emergency Download (EDL) or Qualcomm Download (QDL) mode. This loader is a low-level interface typically used for flashing firmware and performing device recovery. The vulnerability arises because the device does not restrict access to this loader, allowing an attacker with physical access to the device to connect via EDL/QDL mode and flash arbitrary firmware images. This capability enables the attacker to dump device partitions, bypass bootloader protections, and circumvent operating system security controls. Essentially, the attacker can gain persistent control over the device by replacing or modifying its firmware, potentially implanting malicious code or extracting sensitive data stored on the device. The vulnerability is classified under CWE-616 (Reachable Assertion), indicating that the device's security assumptions can be bypassed through this interface. The CVSS 3.1 score is 5.4 (medium), reflecting that exploitation requires physical access (AV:P), no privileges (PR:N), low attack complexity (AC:L), and user interaction (UI:R). The impact on confidentiality is low, but integrity is high since firmware can be altered, and availability impact is low. No known exploits are reported in the wild yet, and no patches have been published at the time of analysis.

For European organizations deploying Flock Safety Bravo Edge AI Compute Devices, this vulnerability poses a significant risk if devices are physically accessible to attackers. The ability to flash arbitrary firmware and bypass bootloader security controls can lead to unauthorized persistent access, data exfiltration, and manipulation of device functions. Given that these devices are likely used for AI-driven safety and surveillance applications, compromise could undermine security monitoring, lead to false data reporting, or disable safety features. This could have operational impacts, especially in critical infrastructure, law enforcement, or public safety contexts. The physical access requirement limits remote exploitation risk but does not eliminate insider threats or attacks in environments where devices are deployed in publicly accessible or insufficiently secured locations. The medium severity rating suggests that while the threat is serious, it is not trivially exploitable remotely, but the consequences of exploitation on device integrity are substantial.

To mitigate CVE-2025-59402, European organizations should implement strict physical security controls to prevent unauthorized access to Flock Safety Bravo Edge devices. This includes securing device enclosures, deploying tamper-evident seals, and restricting access to authorized personnel only. Network segmentation and monitoring should be used to detect anomalous device behavior that might indicate firmware tampering. Organizations should engage with the vendor to obtain firmware updates or patches that disable or authenticate access to the default Firehose loader in EDL/QDL mode. If no patch is available, consider deploying device-level protections such as hardware security modules or secure boot mechanisms that validate firmware integrity at startup. Additionally, maintain an inventory of deployed devices and conduct regular physical inspections. Incident response plans should include procedures for detecting and responding to firmware compromise. Finally, consider alternative devices with stronger firmware security if the risk cannot be adequately mitigated.
