- Title: FortiOS Buffer Overflow Exploited in the Wild
- Detail: A buffer overflow in FortiOS that was exploited by attackers to compromise FortiGate devices.
- Link: Fortinet PSIRT Advisory
- Detail: Devices based on older Silicon Labs chipsets (100, 200, 300 series) lack encryption.
- Potential Impact: Attackers can take control of devices or cause a denial of service.
- Mitigation: Use 500 or 700 series chipsets that support Security 2 (S2) encryption.
- Detail: Attackers can capture Z-Wave transmissions and replay them.
- Potential Impact: Unauthorized control of devices.
- Mitigation: Implement rolling codes or unique transmission identifiers to prevent replay attacks.
- Detail: Jamming attacks target the radio frequency spectrum used by Z-Wave (908.42 MHz in North America) to interfere with communication.
- Potential Impact: Prevents devices from communicating, which could disable security systems or block emergency signals from sensors.
- Mitigation: Use Z-Wave gateways that support heartbeat monitoring, which detects if devices stop responding due to signal interference. Some newer systems use adaptive frequency hopping to mitigate jamming.
- Detail: Attackers can include an unauthorized node in a Z-Wave network (e.g., by using debugging tools to exploit insecure pairing processes).
- Potential Impact: A rogue node can act as a relay for monster-in-the-middle attacks, intercepting and modifying traffic between devices.
- Mitigation: Use Out-of-Band (OOB) authentication for secure pairing. Some modern controllers allow users to verify and approve new devices before integration.
- Detail: An attacker can introduce a malicious Z-Wave device into a network that behaves like a legitimate sensor but actually manipulates or disrupts communication.
- Potential Impact: Unauthorized access, data exfiltration, disruption of automation routines, and potential gateway compromise.
- Mitigation: Only purchase Z-Wave devices from trusted vendors. Use Z-Wave security mode (S2 encryption) to restrict device interactions.
- Detail: Some Z-Wave controllers allow devices to be remotely paired (add-mode) for easier user setup. Attackers can exploit this by remotely forcing a controller into pairing mode.
- Potential Impact: An attacker could remotely enroll unauthorized devices into a network, taking control of smart home systems.
- Mitigation: Disable remote inclusion mode unless actively adding a new device. Ensure controllers require physical confirmation (such as pressing a button) for device pairing.
- Detail: Attackers can flood a Z-Wave network with bogus traffic or abuse routing mechanisms to degrade network performance.
- Potential Impact: Delayed or failed automation commands, making security devices unresponsive (e.g., motion sensors failing to trigger alarms).
- Mitigation: Use network segmentation and regularly monitor logs for unusual traffic spikes.
- Detail: Some devices support remote firmware updates (FOTA), which can be vulnerable to malicious updates if not properly secured.
- Potential Impact: Attackers could install malware or backdoors on devices, leading to persistent threats.
- Mitigation: Only allow signed firmware updates from the manufacturer. Keep all devices firmware up to date.
