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
Cisco Aironet Access Point Software 8.2(100.0) on 1830e, 1830i, 1850e, 1850i, 2800, and 3800 access points allows local users to obtain Linux root access via crafted CLI command parameters, aka Bug ID CSCuy64037.

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

Local privilege escalation vulnerability in Cisco Aironet Access Point software allowing authenticated local users to gain root access on the underlying Linux OS through specially crafted CLI command parameters on 1830e, 1830i, 1850e, 1850i, 2800, and 3800 models.

MitigationApply Cisco software updates when available; restrict physical and console access to trusted personnel to reduce attack surface until patched.

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 access point model
    Run 'show version' or 'show inventory' in the CLI to confirm the model number is one of: 1830e, 1830i, 1850e, 1850i, 2800, or 3800
    Affected if Model number matches one of the affected models listed in the CVE
  2. Check software version
    Run 'show version' to display the Cisco Aironet Access Point Software version
    Affected if Software version equals 8.2_(100.0)
  3. Verify CLI access is enabled
    Check if the CLI interface is accessible via console, SSH, or telnet by attempting to connect or reviewing the configuration with 'show running-config | include line'
    Affected if CLI access (console, SSH, or telnet) is enabled and reachable
  4. Confirm local authentication is possible
    Review user accounts configured on the device using 'show running-config | include username' or check privilege levels
    Affected if Local user accounts exist with privilege level that permits CLI command execution

The environment is affected if the access point model is one of the vulnerable models (1830e, 1830i, 1850e, 1850i, 2800, 3800), the software version is exactly 8.2_(100.0), and CLI access with local authentication is available to untrusted users.
