Security readout for executives and security teams
Plain-English summary
This CVE lets an attacker run commands on a vulnerable Yi Home Camera 2 by abusing how cloud OTA setup handles a Wi-Fi SSID. The attacker needs the camera to connect to a specially crafted SSID, either by proximity and setup manipulation or by convincing a user to connect it.
Executive priority
Treat as high priority where these cameras protect sensitive spaces or share networks with business systems. The issue has severe impact, but urgency should be based on confirmed affected firmware and realistic Wi-Fi proximity or setup exposure.
Technical view
CVE-2018-3910 is a command injection in cloud OTA setup for Yi Technology Home Camera 27US firmware 1.8.7.0D. The CVSS 3.0 vector is adjacent network, low complexity, no privileges, user interaction required, changed scope, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to Yi Technology Home Camera 27US devices running firmware 1.8.7.0D. Risk is highest during camera setup, reconfiguration, or environments where an attacker can influence Wi-Fi SSID selection near the device.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. Exploitation requires the camera to connect to a crafted SSID, so practical attacks likely depend on Wi-Fi proximity, setup timing, or user persuasion.
Researcher notes
The source bundle identifies command injection through SSID handling in cloud OTA setup. Do not assume other Yi models or firmware versions are affected without evidence. No patch details are included in the provided sources, so remediation should be verified against vendor guidance.
Mitigation direction
- Inventory Yi Home Camera 27US devices and record firmware versions.
- Check Yi and Talos guidance for fixed firmware or vendor-supported remediation.
- Do not connect cameras to unknown or user-supplied SSIDs.
- Isolate camera networks from sensitive corporate systems.
- Retire or replace affected devices if no supported update is available.
Validation and detection
- Confirm whether any Yi Home Camera 27US devices run firmware 1.8.7.0D.
- Review provisioning procedures for exposure to untrusted SSIDs.
- Check wireless environments around sensitive sites for suspicious SSID activity.
- Verify camera VLANs cannot reach sensitive internal systems.
- Document whether vendor remediation exists for each deployed device.
