CVE-2024-20767 Adobe CVE debrief

Who should care

Security and platform teams responsible for Adobe ColdFusion deployments, especially internet-facing instances, patch management owners, and incident response teams tracking CISA KEV items.

Technical summary

The supplied corpus identifies the issue only as an improper access control vulnerability in Adobe ColdFusion and marks it as known exploited by CISA. No version ranges, CVSS score, or exploit mechanics are provided in the source corpus, so defensive handling should focus on identifying affected ColdFusion installations, applying Adobe’s mitigations, and reducing exposure until remediation is complete.

Defensive priority

High - CISA KEV-listed and due for action by 2025-01-06.

Recommended defensive actions

• Identify all Adobe ColdFusion instances, including test, staging, and externally reachable systems.
• Review Adobe’s security guidance for APSB24-14 and apply the vendor-recommended mitigations or fixes as soon as possible.
• If mitigations are unavailable or cannot be applied promptly, discontinue use of the product as CISA advises.
• Validate that any internet-facing ColdFusion services are restricted behind authentication, network controls, and other compensating safeguards.
• Confirm remediation completion before the CISA KEV due date of 2025-01-06 and document the result in asset and vulnerability tracking systems.

Evidence notes

This debrief is based on the CISA Known Exploited Vulnerabilities entry for Adobe ColdFusion, published and modified on 2024-12-16. The KEV metadata names the issue as an Adobe ColdFusion improper access control vulnerability, sets the due date to 2025-01-06, and states the required action is to apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
