Authenticated file disclosure via unsanitized image paths
Published Jan 12, 2024 · Updated Nov 14, 2024
Path traversal in Lif Platforms Lif Authentication Server allows remote authenticated users to read server files through image routes. The get_pfp and get_banner handlers concatenate an unvalidated username path segment beneath user_images and return any resulting file found by FileResponse. A low-privileged account and crafted relative path are required; exposure is limited to files readable by the service process.
