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
The InFocus IN3128HD projector with firmware 0.26 allows remote attackers to bypass authentication via a direct request to main.html.

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

The InFocus IN3128HD projector with firmware 0.26 contains an authentication bypass vulnerability where directly accessing main.html circumvents the login mechanism, allowing unauthenticated remote attackers to access the device administrative interface.

MitigationUpdate the projector firmware to a patched version once available. Until then, restrict network access to the projector by placing it behind a firewall or VLAN to minimize exposure to remote attackers.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 projector model
    Access the projector's web interface or check the device label to confirm the model is InFocus IN3128HD
    Affected if The device is not an InFocus IN3128HD model
  2. Check the firmware version
    Access the projector's web administration interface or check via telnet/serial console and locate the firmware version information. Compare against version 0.26.
    Affected if Firmware version is exactly 0.26
  3. Verify the web interface is enabled
    Attempt to access the projector web interface on the default HTTP port (typically 80) via the network IP address
    Affected if The web interface is accessible on the network
  4. Test authentication bypass
    Navigate directly to main.html (for example: http://[projector-ip]/main.html) without logging in and observe if the administrative interface loads without requiring credentials
    Affected if main.html loads the admin interface without any login prompt

The device is affected if it is an InFocus IN3128HD projector running firmware version 0.26 with its web interface accessible on the network, where directly accessing main.html bypasses the login requirement.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update the projector firmware to a patched version once available. Until then, restrict network access to the projector by placing it behind a firewall or VLAN to minimize exposure to remote attackers.
