CVE-2025-64897: 
Adobe ColdFusion vulnerability analysis and mitigation

CVE-2025-64897 is an Improper Access Control vulnerability (CWE-284) in Adobe ColdFusion that allows a low-privileged local attacker to bypass security measures and gain limited unauthorized write access, potentially resulting in denial of service. It affects ColdFusion versions 2021 (through Update 22), 2023 (through Update 16), and 2025 (through Update 4). The vulnerability was disclosed on December 9, 2025, as part of Adobe's security advisory APSB25-105. It carries a CVSS v3.1 base score of 5.6 (Medium), assigned by Adobe (Adobe Advisory).

The vulnerability is classified as CWE-284 (Improper Access Control), meaning the application fails to properly restrict access to resources or functionality for low-privileged users. Exploitation requires local access with low privileges and user interaction, limiting the attack vector to the local system (AV:L). The flaw allows an attacker to bypass existing security controls and gain unauthorized write access to the system, with no confidentiality impact but potential high availability impact (denial of service) and limited integrity impact (Adobe Advisory). No public technical write-ups or proof-of-concept code have been identified at this time.

Successful exploitation of CVE-2025-64897 could allow a low-privileged local attacker to bypass security controls and gain unauthorized write access to the ColdFusion system, potentially causing a denial of service condition. There is no confidentiality impact (no data exposure), but integrity is partially affected through limited unauthorized writes. The vulnerability's local attack vector and user interaction requirement significantly constrain its scope, reducing the risk of broad lateral movement or remote exploitation (Adobe Advisory).

Adobe has released patches addressing CVE-2025-64897 via security advisory APSB25-105. Users should update to ColdFusion 2021 Update 23 or later, ColdFusion 2023 Update 17 or later, or ColdFusion 2025 Update 5 or later. As additional hardening measures, administrators should restrict and monitor user privileges, implement strong access controls, and limit user interactions with potentially vulnerable components (Adobe Advisory).

The vulnerability was noted in CIS's advisory covering multiple Adobe product vulnerabilities released in December 2025, and Sophos referenced it in their December 2025 Patch Tuesday roundup (Sophos Blog). No significant independent researcher commentary or notable social media discussion specific to CVE-2025-64897 has been identified, consistent with its medium severity rating and local-only attack vector.
