CVE-2023-40513Network attack vector

Sensitive file disclosure via unchecked image path

Published May 3, 2024 · Updated Sep 18, 2024

Path traversal in LG Electronics Simple Editor 3.21.0 allows remote attackers to read sensitive files through a crafted image filename. UserManageController.getImageByFilename passes a user-supplied path to file operations without validating that it remains in an allowed directory. The endpoint requires authentication, but the existing authentication mechanism can be bypassed, exposing files readable by the SYSTEM context.
