Technical details
An authenticated path traversal flaw in OFBiz's catalog image management component fails to properly validate file paths, allowing an authenticated attacker to write files outside the intended upload directory using traversal sequences (e.g., ../ payloads). Exploitation requires valid user authentication and image upload capability, and grants arbitrary file write access on the server filesystem.
