Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

SI-10 directly prevents unrestricted uploads of dangerous files like web shells by validating all inputs for consistency and malicious content in the WordPress plugin's upload functionality.

prevent

SI-9 mitigates the vulnerability by restricting dangerous file types from being uploaded through the unauthenticated Elementor Forms plugin endpoint.

preventdetect

SI-3 protects against web shell uploads by deploying malicious code scanning at system entry points such as the plugin's file upload interface.

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.
T1100 Web Shell Persistence
A Web shell is a Web script that is placed on an openly accessible Web server to allow an adversary to use the Web server as a gateway into a network.
Why these techniques?

Unrestricted file upload vulnerability in public-facing WordPress plugin directly enables web shell deployment (T1100) via exploitation of exposed application (T1190).

Deeper analysisAI

CVE-2025-49387 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) in the WordPress plugin Drag and Drop File Upload for Elementor Forms (drag-and-drop-file-upload-for-elementor-forms). This issue affects all versions from n/a through 1.5.3 and allows attackers to upload a web shell to the web server. The vulnerability carries a CVSS v3.1 base score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H), indicating critical severity due to its network accessibility, low attack complexity, lack of privileges or user interaction requirements, and scoped impact with high confidentiality, integrity, and availability consequences.

An unauthenticated attacker can exploit this vulnerability over the network with low complexity and no user interaction. Exploitation enables the upload of dangerous files, such as web shells, directly to the web server, potentially granting remote code execution and full server compromise.
