Unauthenticated file deletion via unvalidated paths
Published May 3, 2024 · Updated Sep 18, 2024
Path traversal in LG Simple Editor 3.21.0 and earlier allows remote attackers to delete arbitrary files through putCanvasDB. The putCanvasDB method accepts a user-supplied path without restricting it to an intended directory before performing a file operation. No authentication is required, and successful exploitation deletes attacker-chosen files with SYSTEM privileges, disrupting application or host operation.
