CVE-2025-65471 is an arbitrary file upload vulnerability identified in the /admin/manager.php component of EasyImages 2.0 version 2.8.6 and earlier. This vulnerability allows an attacker with limited privileges (PR:L) to upload a maliciously crafted PHP file to the server without requiring any user interaction (UI:N). The uploaded file can then be executed on the server, enabling remote code execution (RCE). The vulnerability stems from improper validation and sanitization of uploaded files, classified under CWE-434 (Unrestricted Upload of File with Dangerous Type). The attack vector is network-based (AV:N), meaning the attacker can exploit it remotely over the internet. The vulnerability affects the confidentiality, integrity, and availability of the affected system, as attackers can execute arbitrary code, potentially leading to data theft, system manipulation, or denial of service. The CVSS v3.1 base score is 8.8, indicating a high severity level. No patches or fixes are currently listed, and no known exploits have been reported in the wild as of the publication date (December 11, 2025). However, the vulnerability's characteristics suggest it could be exploited rapidly once weaponized. The affected versions are not explicitly detailed beyond the version 2.8.6 and below, so organizations using EasyImages should verify their version status. The vulnerability is particularly critical because it does not require user interaction and can be exploited remotely with low attack complexity. The lack of authentication requirement is mitigated by the presence of limited privileges, but if the admin interface is exposed or credentials are compromised, exploitation becomes trivial. This vulnerability poses a significant risk to web servers running EasyImages, especially those exposing the admin interface to the internet without adequate protections.

For European organizations, the impact of CVE-2025-65471 can be severe. Successful exploitation leads to remote code execution, allowing attackers to gain full control over affected servers. This can result in data breaches, defacement, service disruption, or use of compromised servers as a foothold for lateral movement within corporate networks. Organizations relying on EasyImages for content management or image handling in their web infrastructure may face operational downtime and reputational damage. Given the high confidentiality, integrity, and availability impact, sensitive data hosted on vulnerable systems could be exposed or manipulated. The vulnerability also increases the risk of ransomware deployment or supply chain attacks if attackers pivot from compromised servers. European data protection regulations such as GDPR impose strict requirements on data security; breaches resulting from this vulnerability could lead to significant legal and financial penalties. The lack of known exploits currently provides a window for proactive mitigation, but the vulnerability's characteristics suggest it could be rapidly exploited once publicly weaponized. Organizations with exposed admin interfaces or weak access controls are particularly at risk.

1. Immediate Actions: Restrict access to the /admin/manager.php interface using network-level controls such as IP whitelisting, VPNs, or firewall rules to limit exposure to trusted personnel only. 2. Patch Management: Monitor EasyImages vendor communications closely and apply security patches or updates as soon as they become available. 3. File Upload Controls: Implement strict server-side validation of uploaded files, including checking MIME types, file extensions, and scanning for malicious content. 4. Privilege Management: Enforce strong authentication and authorization controls for admin interfaces, including multi-factor authentication (MFA) and least privilege principles. 5. Web Application Firewall (WAF): Deploy and configure a WAF to detect and block malicious file upload attempts targeting the vulnerable endpoint. 6. Monitoring and Detection: Enable detailed logging and monitor for unusual file uploads or execution patterns on web servers hosting EasyImages. 7. Incident Response Preparation: Develop and test incident response plans specific to web application compromise scenarios. 8. Network Segmentation: Isolate web servers running EasyImages from critical internal systems to limit lateral movement in case of compromise. 9. Backup and Recovery: Maintain regular, secure backups of affected systems and verify restoration procedures to minimize downtime after an incident. 10. Vendor Communication: Engage with EasyImages support or community forums for updates and mitigation advice.
