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 2023.9, 2021.15 and earlier are affected by a Deserialization of Untrusted Data vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could exploit this vulnerability by providing crafted input to the application, which when deserialized, leads to execution of malicious code. Exploitation of this issue does not require user interaction.

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 2023.9, 2021.15 and earlier contain a deserialization vulnerability where untrusted crafted input is deserialized, leading to arbitrary code execution in the context of the current user without requiring user interaction.

MitigationUpdate ColdFusion to patched versions (2023.10 or later, 2021.16 or later) to remediate this critical deserialization vulnerability.

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 ColdFusion 2023 installed version
    Check the ColdFusion 2023 installation for its version number (typically via administrator console, installer, or version file in the installation directory)
    Affected if The installed version is 2023.9 or earlier, or any build below 2023.10
  2. Identify ColdFusion 2021 installed version
    Check the ColdFusion 2021 installation for its version number (typically via administrator console, installer, or version file in the installation directory)
    Affected if The installed version is 2021.15 or earlier, or any build below 2021.16
  3. Verify ColdFusion update availability
    Check for available ColdFusion updates through the ColdFusion Administrator interface or Adobe's update mechanism
    Affected if A newer version (2023.10+, 2021.16+) is available but not yet installed

The environment is affected if ColdFusion 2023 is at version 2023.9 or earlier, or ColdFusion 2021 is at version 2021.15 or earlier, as these versions contain the vulnerable deserialization component.

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

Update ColdFusion to patched versions (2023.10 or later, 2021.16 or later) to remediate this critical deserialization vulnerability.

Recommended fix High confidence

ColdFusion 2023 version 10 or later; ColdFusion 2021 version 16 or later

  1. 1. Back up your existing ColdFusion installation, including all configurations, applications, and data.
  2. 2. Download the ColdFusion 2023 update (version 10 or later) or ColdFusion 2021 update (version 16 or later) from the official Adobe downloads page at helpx.adobe.com
  3. 3. Review the update's release notes for any specific pre-installation requirements or known issues.
  4. 4. Stop the ColdFusion server services before applying the update.
  5. 5. Apply the update by running the installer on your server.
  6. 6. After installation, restart the ColdFusion services.
  7. 7. Verify the update was successful by checking the ColdFusion administrator console and confirming the version number.
  8. 8. Test critical applications to ensure functionality is maintained.
Caveat Review Adobe's release notes for each update as some updates may include changes to deprecated features or configuration requirements
