Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Timely remediation of the specific flaw in EasyImages 2.0 /admin/manager.php directly eliminates the arbitrary PHP file upload vulnerability.

SI-10 Information Input Validation good match

prevent

Validates uploaded files to restrict dangerous types like PHP and ensure only safe image content is accepted, directly preventing exploitation of the unrestricted upload.

SI-3 Malicious Code Protection good match

preventdetect

Malicious code protection at system entry points scans and blocks crafted PHP shells during upload to the vulnerable manager.php component.

NVD Description

An arbitrary file upload vulnerability in the /admin/manager.php component of EasyImages 2.0 v2.8.6 and below allows attackers to execute arbitrary code via uploading a crafted PHP file.

Deeper analysisAI

CVE-2025-65471 is an arbitrary file upload vulnerability in the /admin/manager.php component of EasyImages 2.0 versions 2.8.6 and below. The flaw enables attackers to upload crafted PHP files, resulting in arbitrary code execution on the affected system. It carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type). The vulnerability was published on 2025-12-11.

Exploitation requires network access, low attack complexity, and low privileges, such as an authenticated user with access to the admin manager interface. No user interaction is necessary, and the scope remains unchanged. Successful attacks achieve high impacts across confidentiality, integrity, and availability, allowing remote code execution on the server.
