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
A vulnerability in Cisco Aironet Access Points (APs) Software could allow an unauthenticated, remote attacker to gain unauthorized access to a targeted device with elevated privileges. The vulnerability is due to insufficient access control for certain URLs on an affected device. An attacker could exploit this vulnerability by requesting specific URLs from an affected AP. An exploit could allow the attacker to gain access to the device with elevated privileges. While the attacker would not be granted access to all possible configuration options, it could allow the attacker to view sensitive information and replace some options with values of their choosing, including wireless network configuration. It would also allow the attacker to disable the AP, creating a denial of service (DoS) condition for clients associated with the AP.

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

Cisco Aironet Access Points contain insufficient access control enforcement on certain URLs, allowing unauthenticated remote attackers to bypass authentication and gain elevated privileges. The attacker can view sensitive configuration data, modify wireless network settings, and potentially disable the AP entirely causing DoS.

MitigationApply the relevant Cisco patch for CVE-2019-15260 immediately. If no patch available, consider network segmentation or replacement of affected hardware.

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 Cisco Aironet model
    Log into the AP CLI and run 'show version' or check the device label to confirm the model number (1540, 1560, 1800, 2800, 3800, or 4800 series)
    Affected if Model is one of the affected series
  2. Determine firmware version
    In the AP CLI, run 'show version' to display the running firmware version. Alternatively, access the web interface and navigate to the Administration or Status page to view the software version
    Affected if Firmware version is not visible or cannot be retrieved from the device
  3. Compare version to affected ranges
    Take the firmware version shown in 'show version' output and compare against the vulnerable ranges: 8.5.x (any version < 8.5.151.0) or 8.8.x (any version < 8.8.120.0)
    Affected if The installed firmware version falls within >= 8.5, < 8.5.151.0 OR >= 8.8, < 8.8.120.0

You are affected if your Cisco Aironet AP (model 1540/1560/1800/2800/3800/4800) runs firmware version 8.5.x before 8.5.151.0 or 8.8.x before 8.8.120.0.

Upgrade available Upgrade to 8.5.151.0 / 8.8.120.0 or later

Interim mitigation

Apply the relevant Cisco patch for CVE-2019-15260 immediately. If no patch available, consider network segmentation or replacement of affected hardware.

Recommended fix High confidence

Upgrade to firmware 8.5.151.0 or later (if on 8.5.x branch); or upgrade to firmware 8.8.120.0 or later (if on 8.8.x branch)

  1. Identify the current firmware version running on the affected Cisco Aironet Access Point model
  2. If running firmware version 8.5.x (less than 8.5.151.0), download and install firmware version 8.5.151.0 or later from Cisco's software download center
  3. If running firmware version 8.8.x (less than 8.8.120.0), download and install firmware version 8.8.120.0 or later from Cisco's software download center
  4. After upgrading, verify the firmware version has been successfully applied by checking the AP's system information
  5. Ensure the AP's management interface is not directly exposed to untrusted networks as an additional hardening measure
Caveat Standard firmware upgrade procedure; ensure backup of AP configuration before upgrade and plan for brief service interruption during the upgrade process
