CVE-2025-34100 Details
Description
An unrestricted file upload vulnerability exists in BuilderEngine 3.5.0 via the integration of the elFinder 2.0 file manager and its use of the jQuery File Upload plugin. The plugin fails to properly validate or restrict file types or locations during upload operations, allowing an attacker to upload a malicious .php file and subsequently execute arbitrary PHP code on the server under the context of the web server process. While the root vulnerability lies within the jQuery File Upload component, BuilderEngine’s improper integration and lack of access controls expose this functionality to unauthenticated users, resulting in full remote code execution.
A remote code execution vulnerability has been identified in BuilderEngine CMS version 3.5.0. This issue arises from an unrestricted file upload vulnerability, which is a result of the integration of the elFinder 2.0 file manager and the jQuery File Upload plugin. The jQuery File Upload plugin does not properly validate or restrict file types or locations during upload, allowing attackers to upload malicious PHP files. These files can then be executed on the server under the web server process's context. The vulnerability is exacerbated by BuilderEngine's improper integration and lack of access controls, exposing this flaw to unauthenticated users.
Users are advised to configure the file upload handler to accept only specific file types, such as GIF, JPEG, and PNG. Additionally, upload features should be restricted to trusted hosts, and an .htaccess file can be used to block execution of uploaded files in untrusted directories.
