CVE-2025-43565 is a high-severity vulnerability affecting multiple versions of Adobe ColdFusion, specifically versions 2025.1, 2023.13, 2021.19, and earlier. The vulnerability is classified as an Incorrect Authorization issue (CWE-863), which means that the application fails to properly enforce access control policies. This flaw allows a high-privileged attacker to bypass security protections and execute arbitrary code within the context of the current user. The vulnerability requires user interaction to be exploited, indicating that an attacker must trick or convince a user to perform some action that triggers the exploit. The scope of the vulnerability is changed, implying that the exploit can affect resources beyond the initially compromised component, potentially impacting the broader system or network environment. The CVSS v3.1 base score is 8.4, reflecting a high severity level. The vector string (AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H) indicates that the attack can be performed remotely over the network with low attack complexity, but requires high privileges and user interaction. The vulnerability impacts confidentiality, integrity, and availability, allowing an attacker to execute arbitrary code, which could lead to full system compromise depending on the privileges of the exploited user. No known exploits are currently reported in the wild, and no patches or mitigation links are provided in the source data, suggesting that organizations must monitor for updates from Adobe and apply them promptly once available.

For European organizations, this vulnerability poses a significant risk, especially for those relying on Adobe ColdFusion for web application development and deployment. Exploitation could lead to unauthorized code execution, data breaches, service disruption, and potential lateral movement within corporate networks. Given the high privileges required, internal threat actors or compromised privileged accounts could leverage this flaw to escalate attacks. The requirement for user interaction means phishing or social engineering could be used to trigger the exploit. Sensitive sectors such as finance, healthcare, government, and critical infrastructure in Europe could face severe operational and reputational damage if targeted. Additionally, the changed scope of the vulnerability increases the risk of widespread impact beyond the initially affected ColdFusion component, potentially affecting integrated systems and data repositories. The absence of known exploits in the wild currently provides a window for proactive defense, but the high CVSS score demands urgent attention to prevent exploitation.

European organizations should implement the following specific mitigations: 1) Immediately inventory all Adobe ColdFusion instances and identify affected versions (2025.1, 2023.13, 2021.19, and earlier). 2) Monitor Adobe’s official security advisories closely and apply patches or updates as soon as they become available. 3) Restrict access to ColdFusion administrative interfaces and services to trusted networks and users only, using network segmentation and firewall rules. 4) Enforce the principle of least privilege for all ColdFusion users and service accounts to minimize the impact of a compromised high-privilege account. 5) Implement strong user awareness training focused on phishing and social engineering to reduce the risk of user interaction exploitation. 6) Enable and review detailed logging and monitoring on ColdFusion servers to detect unusual activities indicative of exploitation attempts. 7) Consider deploying application-layer firewalls or runtime application self-protection (RASP) solutions that can detect and block unauthorized code execution attempts. 8) Conduct regular security assessments and penetration testing focused on ColdFusion environments to identify and remediate potential weaknesses proactively.
