CVE-2025-5058

The eMagicOne Store Manager for WooCommerce plugin exposes a remote management protocol endpoint (?connector=bridge) that allows file uploads to the server. The authentication mechanism relies on a default credential pair (login=1, password=1) and a session key system. If the default credentials are not changed, an attacker can trivially authenticate, obtain a session key, and upload arbitrary files (including PHP shells) to the WordPress root or any writable directory via the set_image task.

CVE-2025-4603

The eMagicOne Store Manager for WooCommerce plugin exposes a remote management protocol endpoint (?connector=bridge) that allows file deletion operations on the server. The authentication mechanism relies on a default credential pair (login=1, password=1) and a session key system. If the default credentials are not changed, an attacker can trivially authenticate, obtain a session key, and delete arbitrary files from the WordPress root or any accessible directory.

Reproduction

A POC CVE-2025-4603.py is provided to demonstrate an attacker deleting wp-config.php.

CVE-2025-4602

The eMagicOne Store Manager for WooCommerce plugin exposes a remote management protocol endpoint (?connector=bridge) that allows file deletion operations on the server. The authentication mechanism relies on a default credential pair (login=1, password=1) and a session key system. If the default credentials are not changed, an attacker can trivially authenticate, obtain a session key, and read arbitrary files from the WordPress root or any accessible directory.

Reproduction

A POC CVE-2025-4602.py is provided to demonstrate reading the wp-config.php file from the server.

CVE-2025-4336

The eMagicOne Store Manager for WooCommerce plugin exposes a remote management protocol endpoint (?connector=bridge) that allows file uploads to the server. The authentication mechanism relies on a default credential pair (login=1, password=1) and a session key system.

Reproduction

  • A POC cve-2025-4336.py is provided to demonstrate a remote attacker uploading a web shell named shell.php via the default authentication mechanism, and executing remote code:

Details

The beaf_options_save action calls the beaf_save_options() function on line 227 of /wp-content/plugins/beaf-before-and-after-gallery/admin/tf-options/classes/BEAF_Settings.php without enforcing any file type validation.

CVE-2024-13869

The Migration, Backup, Staging – WPvivid Backup & Migration plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the upload_files function in all versions up to, and including, 0.9.112. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site’s server which may make remote code execution possible. NOTE: Uploaded files are only accessible on WordPress instances running on the NGINX web server as the existing .htaccess within the target file upload folder prevents access on Apache servers.

Around the time Def Con was happening this year I was sitting at home feeling left out. That made me feel hacky, but I don’t get the same joy from CTFs at the moment that I used to. So, I decided to start hunting for CVEs. That lead to finding CVE-2024-9162, which was just released today, along with the idea for a larger project that has resulted in a few more vulnerabilities yet to be disclosed.

Hack the Box Armageddon Writeup

Introduction

Armageddon is an Easy level box, and it was about as standard as standard can be. The initial foothold was straight a forward Drupal exploit, and the name of the box is a massive hint (Druppalgeddon2). After gaining the initial foothold, enumerating MySQL and credential stuffing gains us user privileges. All of this is pretty basic. The privilege escalation is achieved through snap, which was interesting to me since I’d never done this before. It was not difficult to identify or exploit though.

Hack the Box Ophiuchi Writeup

Introduction

Ophiuchi is a Medium box with a weird name to pronounce. The initial foothold was straight forward but fun, the user flag reminds us to go back to the basics, and the root flag is a difficult mind game for those of us that haven’t even been exposed to the technology.
