Overview
A critical vulnerability, identified as CVE-2025-24447, has been disclosed in Adobe ColdFusion, affecting versions 2025.0, 2023.12, 2021.18, and earlier. The vulnerability results from the deserialization of untrusted data and could allow attackers to execute arbitrary code within the context of the current user. No user interaction is required to exploit this issue, making it particularly dangerous.
Technical Details
This vulnerability is classified under CWE-502: Deserialization of Untrusted Data. When an application deserializes data without verifying its source or integrity, it becomes vulnerable to malicious payloads embedded in serialized objects. In this case, ColdFusion may deserialize crafted input from an attacker, leading to code execution.
The vulnerability is accessible via network and requires no authentication or user interaction. The impact is significant, particularly to confidentiality and integrity, though availability is not directly affected.
