Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly addresses the missing file type validation in ebook_store_save_form by requiring comprehensive validation of uploaded files to block arbitrary dangerous files.

SI-2 Flaw Remediation good match

prevent

Mandates timely remediation and patching of the specific flaw in the Ebook Store plugin up to version 5.8012, eliminating the arbitrary file upload vulnerability.

SI-9 Information Input Restrictions good match

prevent

Enforces restrictions on file uploads such as type, size, and content to prevent unauthenticated attackers from uploading arbitrary files leading to RCE.

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.

Why these techniques?

Arbitrary unauthenticated file upload in public-facing WordPress plugin directly enables exploitation of public-facing application (T1190) and deployment of web shell for RCE (T1505.003).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

The Ebook Store plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the ebook_store_save_form function in all versions up to, and including, 5.8012. This makes it possible for unauthenticated attackers to upload arbitrary…

files on the affected site's server which may make remote code execution possible.
