SSL Pinning Bypass in eWeLink Some hardware products allows local ATTACKER to Decrypt TLS communication and Extract secrets to clone the device via Flash the modified firmware

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

SSL pinning can be bypassed in eWeLink smart home devices by flashing modified firmware, allowing a local attacker to decrypt TLS communications and extract secrets for device cloning.

MitigationImplement SSL pinning using hardware-backed secure storage (e.g., secure element, TPM) or certificate transparency logging to prevent bypass via firmware modification.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device firmware version
    Access the device settings through the eWeLink mobile app or web interface, then navigate to Device Information or About to find the firmware version number.
    Affected if The installed firmware version is older than the version that implements hardware-backed SSL pinning or secure boot protection.
  2. Verify if secure boot is enabled
    Check the device security settings in the eWeLink app or through the device's administrative interface for a 'Secure Boot' or 'Bootloader Protection' option and confirm it is turned on.
    Affected if Secure boot is disabled or not available, allowing modified firmware to be flashed.
  3. Check for hardware security module usage
    Review the device technical specifications or settings for evidence of secure element, TPM, or hardware-backed certificate storage being used for SSL pinning.
    Affected if The device relies solely on software-based certificate storage that can be overwritten with modified firmware.
  4. Confirm SSL pinning is actively enforced
    Inspect the device network settings or diagnostics to verify SSL pinning is enabled. This may be shown as 'Certificate Pinning', 'SSL Verification', or 'TLS Certificate Validation' in the security settings.
    Affected if SSL pinning is disabled, optional, or can be disabled by a user without authentication.
  5. Test for firmware modification protection
    Attempt to access the device's firmware update mechanism and verify if it requires cryptographic signature validation before accepting a firmware image.
    Affected if The device accepts firmware updates without validating cryptographic signatures, allowing bypass of SSL pinning through modified firmware.

The device is affected if it lacks hardware-backed secure storage for SSL certificates, has secure boot disabled, or accepts unsigned firmware updates, enabling an attacker to bypass SSL pinning by flashing modified firmware.
