Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An issue was discovered in SolaX Pocket WiFi 3 through 3.001.02. Authentication for web interface is completed via an unauthenticated WiFi AP. The administrative password for the web interface has a default password, equal to the registration ID of the device. This same registration ID is used as the WiFi SSID name. No routine is in place to force a change to this password on first use or bring its default state to the attention of the user. Once authenticated, an attacker can reconfigure the device or upload new firmware, both of which can lead to Denial of Service, code execution, or Escalation of Privileges.

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 · high confidence

The SolaX Pocket WiFi 3 device uses a default administrative password equal to its registration ID, which is also exposed as the WiFi SSID. Attackers connecting to the unauthenticated WiFi access point can obtain this ID and use it to authenticate with full administrative privileges, allowing firmware uploads or device reconfiguration leading to code execution or denial of service.

MitigationImmediately change the default administrative password on all affected devices and restrict physical/network access to the device's WiFi access point. Consider network segmentation to isolate IoT devices.

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 SolaX Pocket WiFi 3 device
    Scan for WiFi access points and look for SSIDs matching the pattern 'SolaX_*' or similar naming convention associated with SolaX Pocket WiFi 3 devices
    Affected if A WiFi access point with SSID pattern matching SolaX Pocket WiFi 3 is present in the environment
  2. Check device firmware version
    Connect to the device's web interface (typically via the WiFi AP or LAN connection) and navigate to the device information or settings page to view the firmware version
    Affected if The installed firmware version is >= 3.0.0 and <= 3.009.03_20230504
  3. Verify default WiFi SSID contains registration ID
    Examine the WiFi SSID of the SolaX device - the registration ID should be visible as part of or as the full SSID
    Affected if The WiFi SSID contains or equals the device registration ID (typically a numeric identifier)
  4. Test default administrative credential
    Access the device web administration panel and attempt to log in using the registration ID (from the SSID) as both username and password, or as the password with default admin username
    Affected if Authentication succeeds with the registration ID as the password, indicating the default password has not been changed
  5. Confirm WiFi AP is active and accessible
    Verify the device is broadcasting its unauthenticated WiFi access point and is accessible without prior authentication
    Affected if The device WiFi AP is active and allows connection without any pre-authentication

If a SolaX Pocket WiFi 3 device with firmware between 3.0.0 and 3.009.03_20230504 is found with its default WiFi SSID exposing the registration ID, and the admin password still equals that ID, the environment is affected by this vulnerability.
