EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

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.

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every adobe coldfusion deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

  2. Remediation status

    No patch has shipped for CVE-2024-20767 yet — track the adobe coldfusion advisory for a fixed release and apply the workarounds below in the meantime.

  3. Mitigate without a patch

    Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

  4. How O3 protects you

    O3 detects and blocks CVE-2024-20767 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Tailored to CVE-2024-20767. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
