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
ColdFusion versions 2023.6, 2021.12 and earlier are affected by an Improper Access Control vulnerability that could result in arbitrary file system read. An attacker could leverage this vulnerability to access or modify restricted files. Exploitation of this issue does not require user interaction. Exploitation of this issue requires the admin panel be exposed to the internet.

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

ColdFusion versions 2023.6 and earlier contain an improper access control vulnerability allowing arbitrary file system read. Attackers can access or modify restricted files without user interaction, but exploitation requires the admin panel to be exposed to the internet.

MitigationRestrict internet access to the ColdFusion admin panel (ideally, disable external access entirely) and apply vendor patches when available.

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 installed ColdFusion version
    Check the ColdFusion administrator interface or run: cfadmin -version (or check the version file in the ColdFusion installation directory)
    Affected if Version is 2023.x for 2023 or 2021.x for 2021, and the version is 2023.6 or earlier, or 2021.12 or earlier
  2. Determine if admin panel is network accessible
    Attempt to access the ColdFusion administrator URL from an external network or check firewall/network rules for paths like /CFIDE/administrator/ or /cfadmin/
    Affected if The admin interface is reachable from the internet or untrusted networks (not restricted by firewall, VPN, or ACLs)
  3. Verify admin authentication is required
    Attempt to access the admin panel without credentials or check the authentication enforcement configuration
    Affected if The admin panel allows unauthenticated access or authentication can be bypassed

Your environment is affected if you are running ColdFusion 2021.12 or earlier, or 2023.6 or earlier, AND the administrator interface is exposed to the internet or untrusted networks without proper access controls.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Restrict internet access to the ColdFusion admin panel (ideally, disable external access entirely) and apply vendor patches when available.

Recommended fix High confidence

ColdFusion 2021 Update 13+ or ColdFusion 2023 Update 7+

  1. 1. Identify your current ColdFusion version in the Administrator dashboard under 'Server Settings > Settings Summary'
  2. 2. For ColdFusion 2021: Upgrade to Update 13 or later (version 2021.13+)
  3. 3. For ColdFusion 2023: Upgrade to Update 7 or later (version 2023.7+)
  4. 4. Download the latest ColdFusion update from https://helpx.adobe.com/coldfusion/kb/coldfusion-2021-13.html and https://helpx.adobe.com/coldfusion/kb/coldfusion-2023-7.html
  5. 5. Apply the update following Adobe's installation instructions
  6. 6. After update, verify the version in the Administrator console reflects the patched release
  7. 7. As an additional security measure, ensure the ColdFusion Administrator panel is NOT exposed to the internet (restrict to internal networks only)
Caveat Standard ColdFusion update; review Adobe's update notes for any configuration or compatibility considerations
