Loading vulnerability…
BiggiDroid Simple PHP CMS 1.0 contains an unrestricted file upload vulnerability in /admin/editsite.php. By manipulating the 'image' parameter, an attacker can upload arbitrary files without effective server-side restrictions on type/extension/content. The issue is remotely exploitable and a public exploit is available; depending on how uploaded files are stored and handled by the web server, this may enable webshell placement and subsequent remote code execution.

This repository documents a critical arbitrary file upload vulnerability (CVE-2025-15495) in BiggiDroid's Simple PHP Blog CMS. The exploit allows an authenticated attacker to upload a malicious PHP file (web shell) via the admin panel's 'Update Site Logo' functionality. The uploaded file is stored in a web-accessible directory without any extension or MIME type validation, enabling remote code execution by accessing the file directly via HTTP. The proof of concept demonstrates uploading a PHP shell and executing OS commands through the 'cmd' parameter. The repository consists of a detailed README.md with vulnerability analysis, PoC steps, and screenshots, and a placeholder image file. No automated exploit script is provided, but the README includes the full web shell payload and exploitation steps. The attack vector is network-based, targeting the web application's file upload mechanism. The main fingerprintable endpoints are the upload directory and the URL where the shell is accessed. The exploit is a proof of concept and not weaponized.
