CVE-2023-37822: The Eufy Homebase 2 before firmware version 3.3.4.1h creates a dedicated wireless network for its ecosystem...

The Eufy Homebase 2 before firmware version 3.3.4.1h creates a dedicated wireless network for its ecosystem, which serves as a proxy to the end user's primary network. The WPA2-PSK generation of this dedicated network is flawed and solely based on the serial number. Due to the flawed generation process, the WPA2-PSK can be brute forced offline within seconds. This vulnerability allows an attacker in proximity to the dedicated wireless network to gain unauthorized access to the end user's primary network. The only requirement of the attack is proximity to the dedicated wireless network.

Security readout for executives and security teams

Plain-English summary

Eufy Homebase 2 devices before firmware 3.3.4.1h may expose a household or business network through a weak dedicated Wi-Fi network. An attacker nearby could derive the Wi-Fi key from the device serial number and use that network as a route into the primary network.

Executive priority

Treat this as a high-priority IoT network exposure, especially for business sites using consumer security devices. The main urgency is preventing a nearby attacker from turning a camera hub into network access.

Technical view

The Homebase 2 ecosystem network uses WPA2-PSK, but key generation is based only on the serial number. Sources state the PSK can be brute forced offline within seconds. The attack requires radio proximity, no credentials, and no user interaction, with potential confidentiality impact on the primary network.

Likely exposure

Exposure is limited to Eufy Homebase 2 installations running firmware before 3.3.4.1h and within wireless range of an attacker. The source bundle does not list CPEs or broader affected products.

Exploitation context

The source bundle does not show CISA KEV listing or confirmed active exploitation. Practical abuse requires proximity to the device’s dedicated wireless network, making it most relevant for homes, small offices, and sites where attackers can get nearby.

Researcher notes

Evidence supports a weak key-generation issue categorized as CWE-331. The provided CVE data names Homebase 2 before 3.3.4.1h, but affected metadata is incomplete and lists no CPEs. Avoid expanding scope beyond the named product without vendor confirmation.

Mitigation direction

  • Update Eufy Homebase 2 firmware to version 3.3.4.1h or later.
  • Check Anker/Eufy guidance for any additional vendor-specific remediation.
  • Segment IoT devices from sensitive business systems and user workstations.
  • Review nearby Homebase 2 deployments in offices, shared buildings, or exposed locations.

Validation and detection

  • Inventory Eufy Homebase 2 devices and record firmware versions.
  • Confirm all Homebase 2 units are running 3.3.4.1h or later.
  • Identify whether Homebase 2 networks can bridge or proxy into primary networks.
  • Check wireless exposure where attackers could physically get within range.
