CVE-2025-1791Network attack vector

Authenticated arbitrary file write via save_data

Published Mar 1, 2025 · Updated Mar 3, 2025

Unrestricted file upload in SkyCaiji 2.9 allows remote authenticated users to write attacker-supplied files through its administrative interface. The fileAction function in vendor/skycaiji/app/admin/controller/Tool.php processes save_data without enforcing restrictions that prevent dangerous file uploads. A low-privileged authenticated session can reach the function, and successful exploitation permits unauthorized file writes affecting application data and service operation.
