Authenticated code execution via unrestricted PHP upload
Published Aug 29, 2025 · Updated Sep 2, 2025
Unrestricted file upload in WeGIA before 3.4.11 allows remote authenticated users to execute arbitrary code through a crafted spreadsheet. The controla_xlsx.php endpoint writes an uploaded spreadsheet under an attacker-controlled .php filename without adequate extension restrictions. A valid low-privilege account and network access to the endpoint are required; successful execution runs with the web-server user's privileges.
