CVE-2025-64898 is an identified vulnerability in Adobe ColdFusion, a widely used web application development platform. The vulnerability stems from insufficient protection of credentials, classified under CWE-522, which means that credentials are either improperly stored or transmitted in a manner that allows unauthorized access. Affected versions include ColdFusion 2025.4, 2023.16, 2021.22, and earlier releases. The flaw enables an attacker to gain limited unauthorized write access to the system without requiring user interaction or prior authentication, which significantly lowers the barrier to exploitation. The vulnerability impacts the integrity of the system by allowing unauthorized modifications, but it does not directly compromise confidentiality or availability. The CVSS 3.1 base score is 4.3, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but user interaction is required (UI:R). However, the description states no user interaction is needed, which may indicate a slight discrepancy or that exploitation can be automated. No public exploit code or active exploitation has been reported yet. The vulnerability highlights the importance of secure credential management within ColdFusion applications and the need for timely patching once fixes are released. Organizations relying on ColdFusion for critical web applications should review their credential storage mechanisms and monitor for anomalous write operations.

For European organizations, this vulnerability poses a risk primarily to the integrity of web applications running on affected Adobe ColdFusion versions. Unauthorized write access could allow attackers to modify application data, inject malicious code, or alter configurations, potentially leading to further compromise or data manipulation. While confidentiality and availability impacts are limited, integrity breaches can undermine trust, cause operational disruptions, and facilitate subsequent attacks such as privilege escalation or data exfiltration. Organizations in sectors with high reliance on ColdFusion, such as government, finance, and critical infrastructure, may face increased risk. The lack of required authentication and user interaction means attackers can exploit this vulnerability remotely and potentially at scale. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as threat actors often develop exploits post-disclosure. European entities must consider this vulnerability in their risk assessments and incident response planning to prevent exploitation.

1. Immediately inventory all Adobe ColdFusion instances and identify versions 2025.4, 2023.16, 2021.22, and earlier. 2. Apply official patches or updates from Adobe as soon as they become available; monitor Adobe security advisories closely. 3. Until patches are applied, restrict network access to ColdFusion administrative and service ports using firewalls and network segmentation to limit exposure. 4. Review and enhance credential storage practices within ColdFusion applications, ensuring credentials are encrypted at rest and in transit using strong cryptographic methods. 5. Implement strict access controls and audit logging on ColdFusion servers to detect unauthorized write attempts or suspicious activities. 6. Employ web application firewalls (WAFs) with rules tuned to detect anomalous requests targeting ColdFusion endpoints. 7. Conduct regular security assessments and penetration testing focused on credential management and write access controls in ColdFusion environments. 8. Educate development and operations teams about secure credential handling and the risks associated with insufficient protection. 9. Prepare incident response procedures specifically for ColdFusion compromise scenarios to enable rapid containment and remediation.
