CVE-2025-1543Public exploitNetwork attack vector

Authenticated file disclosure via resource path traversal

Published Feb 21, 2025 · Updated Feb 21, 2025

Path traversal in Iteachyou Dreamer CMS 4.1.3 allows remote authenticated users to read server files through resource GET requests. The resource handler accepts ../ segments below /resource/js/ueditor-1.4.3.3 and resolves them outside the intended asset directory. A valid CMS session is required; successful requests disclose readable application files without changing server data.
