Adminer versions prior to 5.4.3 are vulnerable to an unrestricted file upload flaw in the AdminerFileUpload plugin, enabling authenticated users to upload malicious PHP files due to a lax extension allowlist. This vulnerability allows attackers to deploy PHP webshells, potentially executing arbitrary code with the privileges of the web server user. Organizations using affected versions should prioritize patching to mitigate the risk of unauthorized access and code execution.

Original NVD Description

Adminer versions before 5.4.3 contain an unrestricted file upload vulnerability in the AdminerFileUpload plugin that allows authenticated users to upload PHP files by exploiting a permissive default extension allowlist. Attackers can upload PHP webshells to columns ending in _path and execute arbitrary code as the web-server user when uploadPath is web-served.
