Stored XSS via denylist-bypassing file upload
Published Jan 7, 2025 · Updated Jan 8, 2025
Stored XSS in WeGIA before 3.2.7 allows remote attackers to run scripts in a victim's browser through a crafted file upload. The controla_xlsx.php handler rejects only listed extensions, then moves an attacker-named file into a web-accessible directory without validating its MIME type or content. Exploitation requires a victim to open the stored resource and grants the script access to data and actions available in that browser session.
