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 discovered in Acer Wireless Keyboard SK-9662 allows attacker in physical proximity to both decrypt wireless keystrokes and inject arbitrary keystrokes via use of weak encryption.

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 Acer Wireless Keyboard SK-9662 uses weak encryption in its wireless protocol, enabling an attacker within physical proximity to intercept and decrypt keystrokes transmitted wirelessly, as well as inject arbitrary keystrokes back into the connection, effectively allowing keylogging and keystroke injection attacks.

MitigationReplace the affected keyboard with a wired keyboard or a wireless keyboard employing strong encryption (e.g., AES-128 or higher). Until replacement, avoid using the keyboard for sensitive inputs in public or shared spaces.

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 keyboard model
    Physically examine the underside or front of your keyboard for a model number label. The Acer SK-9662 typically has a label showing 'SK-9662' or 'Acer Wireless Keyboard SK-9662'.
    Affected if The model number matches SK-9662 or Acer Sk 9662
  2. Verify wireless connectivity
    Confirm the keyboard is operating wirelessly. The SK-9662 is a wireless keyboard that communicates via a USB receiver or Bluetooth. Check if a small USB dongle is plugged into the computer, indicating active wireless communication.
    Affected if The keyboard is connected and functioning wirelessly via its included USB receiver or Bluetooth adapter
  3. Check for encrypted wireless protocols
    Examine the keyboard documentation or system settings to determine what wireless encryption protocol the keyboard uses. The CVE specifically notes weak encryption in the wireless protocol. If no documentation is available, this indicates the vulnerability cannot be ruled out.
    Affected if The wireless protocol uses weak or undocumented encryption, or encryption details cannot be verified
  4. Assess physical exposure risk
    Determine the keyboard's usage environment. The vulnerability allows attacks from physical proximity, meaning anyone within wireless range could intercept or inject keystrokes.
    Affected if The keyboard is used in shared offices, public spaces, or any environment where untrusted individuals could be within wireless range

If the keyboard model is Acer SK-9662 or Acer Sk 9662 and it is being used wirelessly, the environment is affected by this vulnerability regardless of firmware version since all versions are impacted.
