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 Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker to elevate privileges and execute administrative functions on an affected device. The vulnerability is due to insufficient authorization validation. An attacker could exploit this vulnerability by logging in to an affected device as a low-privileged user and then sending specific HTTPS requests to execute administrative functions using the information retrieved during initial login.

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

A vulnerability in Cisco ASA's web-based management interface allows authenticated low-privileged users to execute administrative functions by sending specific HTTPS requests, due to insufficient authorization validation in the privilege check mechanism.

MitigationApply the Cisco security update for ASA Software; as a defense-in-depth measure, restrict web-based management interface access to trusted administration networks 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 Cisco ASA device
    Access the device console or use 'show version' command to confirm the device is a Cisco Adaptive Security Appliance
    Affected if Device is not a Cisco ASA appliance, this CVE does not apply
  2. Check ASA software version
    Run 'show version' command on the ASA CLI and locate the software version number
    Affected if Version is 8.2 or lower (any version <= 8.2 is affected)
  3. Confirm web-based management is enabled
    Run 'show running-config http' or 'show running-config | include http server enable' to check if the HTTPS management interface is enabled
    Affected if HTTP server is enabled (HTTPS management interface must be active for this vulnerability to be exploitable)
  4. Verify user accounts exist
    Run 'show running-config username' or use ASDM to view configured user accounts
    Affected if Any local or managed user accounts are configured on the ASA

The environment is affected if the Cisco ASA runs software version 8.2 or lower AND has the HTTPS web-based management interface enabled with at least one user account configured.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
