Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Requires timely remediation of the specific flaw in the File Away plugin's upload function via patching to eliminate arbitrary file upload vulnerability.

SI-10 Information Input Validation good match

prevent

Mandates validation of uploaded files to enforce type restrictions, directly countering the missing file type validation in the upload function.

AC-3 Access Enforcement good match

prevent

Enforces access authorizations with capability checks to block unauthenticated attackers from reaching the vulnerable upload function.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1505.003 Web Shell Persistence

Adversaries may backdoor web servers with web shells to establish persistent access to systems.

Why these techniques?

Unrestricted arbitrary file upload in public-facing WordPress plugin directly enables T1190 (exploiting the vulnerable application) and T1505.003 (uploading web shell for RCE).

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

The File Away plugin for WordPress is vulnerable to arbitrary file uploads due to a missing capability check and missing file type validation in the upload() function in all versions up to, and including, 3.9.9.0.1. This makes it possible for…

unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

Deeper analysisAI

CVE-2025-2512 affects the File Away plugin for WordPress in all versions up to and including 3.9.9.0.1. The vulnerability stems from a missing capability check and lack of file type validation in the upload() function, enabling arbitrary file uploads. It has been assigned a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-434 (Unrestricted Upload of File with Dangerous Type). The issue was published on 2025-03-19.

Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction required. By uploading arbitrary files to the affected site's server, they can potentially achieve remote code execution, granting high levels of confidentiality, integrity, and availability impact.

Advisories and related resources, including a Wordfence threat intelligence report, the plugin's developer page on WordPress.org, the vulnerable code location in the plugin's Trac browser, and a public exploit repository on GitHub, provide further details for analysis and response. Security practitioners should consult these references for mitigation guidance, such as updating the plugin if a patch is available.
