## Technical details

This is a path traversal vulnerability (CWE-22) in the file move and rename operations. The vulnerable component fails to properly validate the oldFileName parameter, allowing attackers to use path traversal sequences (e.g., ../) to reference and move files outside the intended document root. The attack requires authentication to access the ICEcoder interface. An authenticated attacker can exploit this to relocate any files writable by the PHP process into the web directory, enabling file disclosure and data deletion. The vulnerability affects ICEcoder through version 8.1.
