CVE-2024-20767: ColdFusion | Improper Access Control (CWE-284)

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.

Security readout for executives and security teams

Plain-English summary

CVE-2024-20767 lets an unauthenticated attacker read, and potentially modify, restricted files on affected Adobe ColdFusion systems when the admin panel is exposed to the internet. CISA lists it in KEV, so exploitation is known. Business urgency is highest for internet-facing ColdFusion administration interfaces.

Executive priority

Treat this as urgent for any internet-facing ColdFusion administration panel. KEV listing means real-world exploitation is known, and the impact includes sensitive file disclosure and possible restricted file modification.

Technical view

Adobe ColdFusion 2023.6, 2021.12, and earlier are affected by CWE-284 improper access control. The CVSS 3.1 score is 7.4: network reachable, high attack complexity, no privileges, no user interaction, with high confidentiality and integrity impact. Source data says exploitation requires internet exposure of the admin panel.

Likely exposure

Organizations running Adobe ColdFusion 2023.6, 2021.12, or earlier with an internet-exposed administration panel are the clearest exposure group. Internal-only admin panels reduce the described attack path, but version status still needs review against Adobe guidance.

Exploitation context

Active exploitation is supported by CISA KEV inclusion. The provided sources do not describe exploitation volume, affected sectors, indicators of compromise, or technical exploit mechanics. Avoid assuming compromise solely from product presence; prioritize exposed admin panels.

Researcher notes

The source bundle supports affected versions, CVSS vector, CWE-284 classification, admin-panel exposure precondition, and KEV status. It does not provide exploit indicators, patch version details, or workaround specifics beyond exposure reduction and vendor guidance review.

Mitigation direction

  • Identify all Adobe ColdFusion instances and their installed update levels.
  • Remove internet exposure from ColdFusion administrator interfaces wherever possible.
  • Review Adobe APSB24-14 and apply vendor-recommended updates or mitigations.
  • Prioritize remediation for systems reachable from the public internet.
  • Use CISA KEV status to drive emergency vulnerability management timelines.

Validation and detection

  • Inventory externally reachable ColdFusion admin panels and map owners.
  • Confirm whether each instance runs ColdFusion 2023.6, 2021.12, or earlier.
  • Check internet-facing access paths, reverse proxies, and firewall rules.
  • Review server logs for suspicious access to restricted files.
  • Document remediation status against Adobe APSB24-14 guidance.
