CVE-2025-64898 is a vulnerability identified in Adobe ColdFusion, specifically affecting versions 2025.4, 2023.16, 2021.22, and earlier. The issue stems from insufficient protection of credentials (classified under CWE-522), where credentials are either improperly stored or transmitted without adequate security controls. This weakness allows an attacker to gain limited unauthorized write access to the system, potentially modifying data or configurations. The attack vector is network-based (AV:N), requiring no privileges (PR:N), but does require user interaction (UI:R), such as triggering a crafted request or exploiting a user session. The vulnerability does not compromise confidentiality or availability but impacts integrity by allowing unauthorized changes. No patches or exploit code are currently publicly available, and no known exploits have been reported in the wild. The vulnerability is rated medium severity with a CVSS 3.1 base score of 4.3, reflecting the limited scope and impact. Adobe ColdFusion is widely used for enterprise web application development, and this vulnerability could be leveraged to alter application behavior or inject malicious content if exploited. The root cause relates to poor credential management practices within ColdFusion, emphasizing the need for secure storage and transmission of sensitive authentication data.

For European organizations, the impact of CVE-2025-64898 includes potential unauthorized modification of web applications or backend configurations hosted on vulnerable ColdFusion servers. This could lead to data integrity issues, unauthorized changes to business logic, or introduction of malicious code, potentially undermining trust in affected services. While confidentiality and availability are not directly impacted, integrity breaches can have cascading effects, including compliance violations under GDPR if personal data processing is affected. Organizations in sectors such as finance, government, and critical infrastructure that rely on ColdFusion for web services may face operational disruptions or reputational damage. The lack of required privileges lowers the barrier for attackers, increasing risk especially if user interaction can be socially engineered. The absence of known exploits currently reduces immediate threat but does not eliminate future risk, making proactive mitigation essential.

1. Monitor Adobe’s official channels for patches addressing CVE-2025-64898 and apply updates promptly once available. 2. Until patches are released, restrict network access to ColdFusion administrative interfaces and credential stores using firewalls and network segmentation. 3. Implement strict access controls and audit logging around credential storage and usage within ColdFusion environments. 4. Encrypt credentials both at rest and in transit using strong cryptographic standards to prevent interception or unauthorized retrieval. 5. Conduct regular security assessments and penetration tests focusing on credential management and write access controls in ColdFusion deployments. 6. Educate users and administrators about social engineering risks to reduce chances of user interaction exploitation. 7. Employ web application firewalls (WAFs) to detect and block suspicious requests targeting ColdFusion servers. 8. Review and minimize the number of users with write permissions to sensitive ColdFusion components. 9. Use multi-factor authentication (MFA) for administrative access to reduce risk of unauthorized access. 10. Maintain up-to-date backups to enable recovery in case of unauthorized modifications.
