FKIE_CVE-2026-24469

Vulnerability from fkie_nvd - Published: 2026-01-24 03:16 - Updated: 2026-04-15 00:35
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
C++ HTTP Server is an HTTP/1.1 server built to handle client connections and serve HTTP requests. Versions 1.0 and below are vulnerable to Path Traversal via the RequestHandler::handleRequest method. This flaw allows an unauthenticated, remote attacker to read arbitrary files from the server's filesystem by crafting a malicious HTTP GET request containing ../ sequences. The application fails to sanitize the filename variable derived from the user-controlled URL path, directly concatenating it to the files_directory base path and enabling traversal outside the intended root. No patch was available at the time of publication.
