CVE-2025-65396 in Flare Camera
Summary
by MITRE • 01/14/2026
A vulnerability in the boot process of Blurams Flare Camera version 24.1114.151.929 and earlier allows a physically proximate attacker to hijack the boot mechanism and gain a bootloader shell via the UART interface. This is achieved by inducing a read error from the SPI flash memory during the boot, by shorting a data pin of the IC to ground. An attacker can then dump the entire firmware, leading to the disclosure of sensitive information including cryptographic keys and user configurations.

This vulnerability represents a critical security flaw in the boot process of Blurams Flare Camera devices running version 24.1114.151.929 and earlier. The issue stems from insufficient protection mechanisms during the device's startup sequence, creating an attack vector that can be exploited by physically proximate adversaries. The vulnerability specifically targets the bootloader phase where the device initializes its operating system and loads critical system components from non-volatile memory. The attack exploits a fundamental weakness in the device's hardware security architecture, particularly in how it handles memory read operations during boot sequence.
The technical implementation of this exploit relies on manipulating the SPI flash memory interface through physical means, specifically by creating a read error condition that forces the bootloader into an interactive shell mode. This is accomplished by shorting a data pin of the SPI flash IC to ground, which generates a specific error condition that the bootloader does not properly handle. This technique falls under the category of hardware-level attacks that bypass traditional software security measures and represents a classic example of insufficient input validation and error handling in embedded systems. The attack requires physical proximity to the device and access to the UART interface, making it a local attack vector that aligns with CWE-254 security weaknesses related to improper error handling.
The operational impact of this vulnerability is severe and multifaceted, as it provides attackers with complete access to the device's firmware contents. When successfully exploited, the attacker can dump the entire firmware image, which typically contains sensitive cryptographic keys, user configurations, device-specific parameters, and potentially proprietary software components. This disclosure creates significant risks for device security, as cryptographic keys can be used to decrypt communications or impersonate the device in network environments. The vulnerability also exposes user configuration data that may include network credentials, access controls, and other sensitive operational parameters. According to ATT&CK framework, this vulnerability maps to T1059.004 (Command and Scripting Interpreter: PowerShell) and T1068 (Exploitation for Privilege Escalation) through the use of the bootloader shell for privilege escalation and system compromise.
The attack scenario begins with an attacker gaining physical access to the target device, typically through social engineering or opportunistic access to the installation location. Once positioned near the device, the attacker uses the SPI flash memory manipulation technique to trigger the bootloader error condition. The resulting bootloader shell provides direct access to the device's memory and firmware, enabling the attacker to extract complete firmware images. This access allows for reverse engineering of the device's software architecture, identification of additional vulnerabilities, and potential exploitation of other system components. The attack chain demonstrates a clear path from physical access to full system compromise, highlighting the importance of secure boot implementations and hardware-level security controls.
Mitigation strategies for this vulnerability must address both the immediate hardware-level issue and broader security architecture concerns. The primary recommendation involves implementing secure boot mechanisms that validate firmware integrity before execution, preventing unauthorized code from running in the bootloader environment. Device manufacturers should also implement proper error handling procedures that prevent the bootloader from entering interactive modes when encountering memory read errors. Additional protections include physical security measures such as tamper detection circuits and secure element integration for cryptographic key storage. Organizations should also consider implementing firmware integrity monitoring systems that can detect unauthorized firmware modifications and alert security personnel to potential compromises. The vulnerability underscores the importance of following industry standards such as NIST SP 800-147 for embedded system security and ISO/IEC 27030 for security risk management in IoT devices.
