Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly requires identification, reporting, and correction of the arbitrary file upload flaw in the WPBookit plugin, eliminating the vulnerability through patching.

SI-10 Information Input Validation good match

prevent

Mandates validation of information inputs such as file types and contents at upload points, directly countering the missing file type validation in image_upload_handle().

AC-14 Permitted Actions Without Identification or Authentication partial match

prevent

Limits and controls permitted actions without identification or authentication, preventing unauthenticated exploitation of the 'add_booking_type' route for file uploads.

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?

Arbitrary unauthenticated file upload in public-facing WP plugin directly enables T1190 exploitation and T1100 web shell deployment for RCE.

NVD Description

The WPBookit plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the image_upload_handle() function hooked via the 'add_booking_type' route in all versions up to, and including, 1.0.4. 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-2025-6058 is an arbitrary file upload vulnerability in the WPBookit plugin for WordPress, stemming from missing file type validation in the image_upload_handle() function, which is hooked via the 'add_booking_type' route. This flaw affects all versions of the plugin up to and including 1.0.4. The vulnerability is rated with 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), published on 2025-07-12.

Unauthenticated attackers can exploit this vulnerability over the network with low complexity and no user interaction required. By leveraging the affected route, they can upload arbitrary files to the WordPress site's server, potentially enabling remote code execution depending on the file type and server configuration.

Advisories and references, including Wordfence threat intelligence and WordPress plugin repository details such as the source code at line 455 in class.wpb-booking-type-controller.php and changeset 3314288, provide technical insights into the vulnerability for mitigation and patching guidance.
