CVE-2023-39141Public exploitNetwork attack vector

Arbitrary file disclosure via unsanitized URL paths

Published Aug 22, 2023 · Updated Oct 3, 2024

Path traversal in webui-aria2 1.0.1 and earlier allows remote attackers to read server files through crafted HTTP request paths. The Node.js server joins the URL pathname to its docs directory without verifying that the resolved path remains inside that directory. An unauthenticated request can therefore disclose any file readable by the server process, including files outside the web root.
