Description

alexusmai laravel-file-manager 3.3.1 and before allows an authenticated attacker to achieve Remote Code Execution (RCE) through a crafted file upload. A file with a '.png` extension containing PHP code can be uploaded via the file manager interface. Although the upload appears to fail client-side validation, the file is still saved on the server. The attacker can then use the rename API to change the file extension to `.php`, and upon accessing it via a public URL, the server executes the embedded code.

Attack-Flow Graph

Executive Summary

This vulnerability in alexusmai laravel-file-manager versions 3.3.1 and earlier allows an authenticated attacker to perform Remote Code Execution (RCE). The attacker uploads a file with a '.png' extension that actually contains PHP code. Although the client-side validation rejects the upload, the file is still saved on the server. The attacker then uses the rename API to change the file extension to '.php'. When the file is accessed via a public URL, the server executes the embedded PHP code, allowing the attacker to run arbitrary code remotely.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary code on the server remotely, potentially leading to full system compromise. This can result in unauthorized access to sensitive data, disruption of services, data loss, or further exploitation of the affected system.
