CVE-2025-6031: Amazon Cloud Cam Auth Bypass Vulnerability

CVE-2025-6031 Overview

CVE-2025-6031 affects the Amazon Cloud Cam, a home security camera deprecated on December 2, 2022. The device reached end-of-life status and no longer receives active vendor support. When powered on, the camera attempts to connect to a remote service infrastructure that has been retired.

The device defaults to a pairing state that allows an arbitrary user to bypass SSL pinning. An attacker on an adjacent network can associate the camera with a network they control. This enables interception and modification of camera traffic. Amazon recommends customers discontinue use of any remaining Cloud Cam units.

Critical Impact
Attackers within wireless range can hijack pairing, bypass SSL pinning, and intercept or modify all camera traffic, compromising confidentiality, integrity, and availability of video and control data.

Affected Products

Amazon Cloud Cam (all firmware revisions)
End-of-life home security camera deprecated on December 2, 2022
Devices still attempting to connect to deprecated AWS service infrastructure

Technical Details for CVE-2025-6031

Vulnerability Analysis

The Amazon Cloud Cam relies on a remote service infrastructure that Amazon retired alongside the product. With the backend gone, the device cannot complete its normal provisioning handshake. It falls back to an always-on pairing state instead of refusing further setup attempts.

In this pairing state, the camera accepts new network associations without enforcing certificate validation against the original service. An attacker on the adjacent network can present a substitute endpoint and complete pairing. Once associated, the attacker controls the upstream path for all camera traffic. The weakness maps to [CWE-672], operation on a resource after expiration or release.

Root Cause

The root cause is the device's failure to handle end-of-life of its dependent cloud service safely. Rather than entering a secure failure mode, the firmware reverts to a pairing posture that disables SSL pinning enforcement. Pinning is meant to bind the device to legitimate Amazon endpoints, but the fallback path removes that binding.

Attack Vector

Exploitation requires adjacent network access, typically wireless proximity to a powered-on Cloud Cam. The attacker advertises a network the camera will join during its pairing fallback. After association, the attacker positions a rogue endpoint that the device accepts because pinning is bypassed. All subsequent video, audio, and control data flow through the attacker-controlled path, enabling interception and modification.

No verified public exploit code is available. See the AWS Security Bulletin AWS-2025-013 for vendor guidance.

Detection Methods for CVE-2025-6031

Indicators of Compromise

Cloud Cam devices associating with Wi-Fi SSIDs other than the owner's authorized network.
Outbound traffic from a Cloud Cam destined to IP addresses outside known AWS ranges.
TLS sessions from the camera terminating at endpoints presenting non-Amazon certificates.
Repeated pairing-mode broadcasts from a Cloud Cam after initial setup.

Detection Strategies

Inventory home and small-office networks for any active Amazon Cloud Cam MAC address prefixes and flag them as end-of-life.
Inspect DHCP and ARP tables for Cloud Cam devices on unexpected VLANs or guest networks.
Monitor wireless probe requests indicating a Cloud Cam still seeking the deprecated provisioning service.

Monitoring Recommendations

Capture and review egress traffic from IoT VLANs for connections to non-AWS destinations originating from camera devices.
Alert on any TLS handshake from a Cloud Cam where the server certificate chain does not match historical Amazon issuers.
Track wireless association events on access points to detect Cloud Cams joining rogue or attacker-controlled SSIDs.

How to Mitigate CVE-2025-6031

Immediate Actions Required

Power off and physically disconnect all Amazon Cloud Cam devices, per Amazon's published guidance.
Remove Cloud Cam entries from home network allowlists, DHCP reservations, and port-forwarding rules.
Replace the camera with a vendor-supported model that receives current firmware updates.
Audit cloud and on-premises inventories for any other end-of-life IoT devices exhibiting similar fallback behavior.

Patch Information

No patch is available. The Amazon Cloud Cam is end-of-life and will not receive a firmware fix. Amazon recommends customers discontinue use of any remaining Cloud Cam devices. Refer to AWS Security Bulletin AWS-2025-013 for the official advisory.

Workarounds

Isolate any still-powered Cloud Cam on a segregated VLAN with no internet egress until decommissioning is complete.
Block the device's MAC address at the wireless access point to prevent pairing-mode association.
Disable Wi-Fi radios on the device by removing power, since software-based pairing cannot be trusted.

bash

# Example: block a Cloud Cam MAC address at the gateway
# Replace AA:BB:CC:DD:EE:FF with the device MAC
iptables -I FORWARD -m mac --mac-source AA:BB:CC:DD:EE:FF -j DROP

# Example: deny the MAC at a hostapd-managed access point
echo "AA:BB:CC:DD:EE:FF" >> /etc/hostapd/hostapd.deny
hostapd_cli -i wlan0 deauthenticate AA:BB:CC:DD:EE:FF
