CVE-2025-65474 is an arbitrary file rename vulnerability identified in the /admin/manager.php component of EasyImages 2.0 version 2.8.6 and earlier. This vulnerability allows an attacker with at least limited privileges (PR:L) to rename a PHP file to an SVG file format, effectively bypassing file type validation mechanisms. By doing so, the attacker can upload or rename a malicious PHP script disguised as an SVG image, which the server may then execute, leading to arbitrary code execution on the affected system. The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L) and does not require user interaction (UI:N). The scope is unchanged (S:U), meaning the impact is confined to the vulnerable component or system. The CVSS v3.1 base score is 8.8, indicating a high severity due to the potential for full compromise of confidentiality, integrity, and availability (C:H/I:H/A:H). The weakness corresponds to CWE-434, which relates to improper handling of file uploads or renames that can lead to security issues. Although no known exploits have been reported in the wild yet, the vulnerability presents a significant risk, especially for web servers running EasyImages with accessible administrative interfaces. The lack of available patches at the time of publication necessitates immediate mitigation through configuration changes and monitoring. This vulnerability is critical for environments where EasyImages is used to manage images and files, as it can be leveraged to gain unauthorized control over the server.

For European organizations, the impact of CVE-2025-65474 can be severe. Exploitation can lead to arbitrary code execution, allowing attackers to gain unauthorized access to sensitive data, modify or delete files, and disrupt services. This compromises confidentiality, integrity, and availability of affected systems. Organizations relying on EasyImages for content management or digital asset handling may face website defacement, data breaches, or ransomware deployment. The vulnerability's ease of exploitation and network accessibility increase the risk of widespread attacks, especially in industries with high-value targets such as finance, healthcare, and government. Additionally, compromised servers could be used as pivot points for lateral movement within networks, amplifying the threat. The absence of known exploits currently provides a window for proactive defense, but the high CVSS score underscores the urgency of addressing this vulnerability to prevent potential damage.

To mitigate CVE-2025-65474, European organizations should implement the following specific measures: 1) Immediately restrict access to the /admin/manager.php interface using network-level controls such as IP whitelisting or VPNs to limit exposure. 2) Enforce strict file type validation on the server side to prevent renaming or uploading of executable files disguised as images, particularly ensuring that PHP files cannot be renamed to SVG or other image formats. 3) Apply the principle of least privilege by limiting user permissions for file management operations within EasyImages, ensuring only trusted administrators have rename capabilities. 4) Monitor file system changes and web server logs for suspicious rename activities or unexpected file extensions in image directories. 5) Deploy web application firewalls (WAFs) with custom rules to detect and block attempts to exploit this vulnerability. 6) Stay alert for vendor patches or updates addressing this issue and apply them promptly once available. 7) Conduct regular security audits and penetration tests focusing on file upload and rename functionalities. These targeted actions go beyond generic advice and directly address the vulnerability's exploitation vectors.
