Authenticated file deletion via traversed image paths
Published Mar 22, 2026 · Updated Mar 22, 2026
Path traversal in SSCMS 4.7.0 allows remote authenticated users to delete arbitrary files through the layerImage endpoint. LayerImageController.Submit accepts attacker-controlled filePaths values and passes the resolved paths to a deletion operation without confining them to the intended image directory. Low-privilege authenticated access to the endpoint is required; exploitation removes server files and can interrupt service, but does not disclose file contents.
