CVE-2025-3268Network attack vector

Unauthenticated content access via numeric URL routing

Published Apr 4, 2025 · Updated Apr 7, 2025

Improper authentication in qinguoyi TinyWebServer 1.0 allows remote attackers to read restricted web content via crafted URL paths. Within http_conn::do_request, the final URL-path character selects picture.html, video.html, or fans.html and copies that resource into m_real_file without checking an authenticated session. Network access alone is sufficient; the published impact is limited to confidentiality, with no documented ability to change data or interrupt service.
