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 the web-based management interface of Cisco ATA 190 Series Multiplatform Analog Telephone Adapter firmware could allow an authenticated, local attacker with low privileges to view passwords on an affected device. This vulnerability is due to incorrect sanitization of HTML content from an affected device. A successful exploit could allow the attacker to view passwords that belong to other users.

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

This is an HTML sanitization vulnerability in the web-based management interface of Cisco ATA 190 Series adapters. A low-privilege authenticated user can exploit improper sanitization of HTML content to view passwords belonging to other users on the same device.

MitigationApply the vendor firmware patch when available. Until then, limit administrative access to trusted personnel only and monitor for unauthorized account access.

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 device model
    Access the web-based management interface or CLI and determine if the device is an ATA 191 or ATA 192 series adapter
    Affected if The device model is Cisco ATA 191 or ATA 192
  2. Check the installed firmware version
    In the web interface, navigate to the System Overview or Administration section to view the firmware version. Alternatively, use the CLI command 'show version' or 'show system-info'
    Affected if The firmware version is lower than 12.0.2 or 11.2.5 for the respective model (ATA 191: < 12.0.2 or < 11.2.5; ATA 192: < 11.2.5)
  3. Verify the web-based management interface is enabled
    Check the device configuration for HTTP or HTTPS management access settings. This is typically found under Administration > Management Access > Web Server or similar path
    Affected if The web-based management interface is enabled and accessible
  4. Confirm multiple user accounts exist
    In the web interface, navigate to the User Accounts or Administration > User Management section to list configured users
    Affected if More than one user account is configured on the device

A user is affected if they are running a Cisco ATA 191 or ATA 192 device with firmware version below 12.0.2 (for ATA 191) or below 11.2.5 (for ATA 191/192), with the web management interface enabled, and with multiple user accounts present on the device.

Upgrade available Upgrade to 11.2.5 / 12.0.2 or later
Fixed in 11.2.512.0.2
Interim mitigation

Apply the vendor firmware patch when available. Until then, limit administrative access to trusted personnel only and monitor for unauthorized account access.

Recommended fix High confidence

ATA 191: upgrade to firmware 12.0.2 or later (or 11.2.5 or later for 11.x branch); ATA 192: upgrade to firmware 11.2.5 or later

  1. 1. Identify the current firmware version of the Cisco ATA 190 Series device by accessing the web-based management interface
  2. 2. Navigate to the Cisco software download page for ATA 190 Series Multiplatform firmware (available at sec.cloudapps.cisco.com)
  3. 3. Download the fixed firmware version: 12.0.2 or later for ATA 191; 11.2.5 or later for ATA 192
  4. 4. Access the web-based management interface of the affected device
  5. 5. Navigate to the firmware upgrade section (typically under Administration > System > Software Upgrade)
  6. 6. Upload and apply the fixed firmware version
  7. 7. After upgrade, verify the device is running the fixed version and confirm the vulnerability is resolved
