CVE-2025-61810 is a deserialization of untrusted data vulnerability (CWE-502) affecting multiple versions of Adobe ColdFusion, specifically versions 2025.4, 2023.16, 2021.22, and earlier. The vulnerability arises when ColdFusion improperly handles serialized data inputs, allowing an attacker with high privileges to craft malicious serialized objects that, when deserialized by the application, lead to arbitrary code execution within the context of the current user. This can result in full compromise of the affected system's confidentiality, integrity, and availability. The attack vector is network-based (AV:N) with low attack complexity (AC:L), but requires high privileges (PR:H) and user interaction (UI:R), and the scope of the impact extends beyond the vulnerable component (S:C). Despite no known exploits in the wild at the time of publication, the vulnerability's characteristics and high CVSS score (8.4) indicate a serious threat. ColdFusion is widely used in enterprise web applications for rapid development and deployment, making this vulnerability particularly dangerous in environments where ColdFusion servers handle sensitive data or critical business processes. The lack of available patches at the time of reporting necessitates immediate defensive measures to mitigate risk.

For European organizations, exploitation of CVE-2025-61810 could lead to unauthorized code execution on ColdFusion servers, potentially resulting in data breaches, service disruption, or lateral movement within networks. Given ColdFusion's role in web application infrastructure, attackers could leverage this vulnerability to compromise sensitive customer data, intellectual property, or critical operational systems. The requirement for high privileges and user interaction somewhat limits the attack surface but does not eliminate risk, especially in environments with multiple users having elevated permissions or where social engineering could facilitate interaction. The scope change means that the impact could extend beyond the initial vulnerable component, affecting other parts of the system or network. This vulnerability could disrupt business continuity and damage organizational reputation, particularly in sectors such as finance, healthcare, and government where ColdFusion is deployed. Additionally, compliance with GDPR and other data protection regulations could be jeopardized if personal data is exposed or manipulated.

European organizations should immediately audit their ColdFusion deployments to identify affected versions (2025.4, 2023.16, 2021.22, and earlier). Until official patches are released, organizations should implement strict input validation and sanitization to prevent malicious serialized data from reaching the deserialization routines. Network-level controls should restrict access to ColdFusion services to trusted users and systems only, employing segmentation and firewall rules. Monitoring and logging should be enhanced to detect anomalous deserialization activities or unusual user interactions. Employing application-layer firewalls or runtime application self-protection (RASP) solutions can help intercept malicious payloads. User privileges should be minimized to reduce the risk of high-privilege exploitation, and multi-factor authentication should be enforced to mitigate social engineering risks. Once Adobe releases patches, organizations must prioritize timely deployment. Additionally, conducting security awareness training focusing on the risks of interacting with untrusted data can reduce the likelihood of successful exploitation requiring user interaction.
