Unauthenticated file disclosure via path traversal
Published Sep 27, 2021 · Updated Aug 4, 2024
Path traversal in e7d Speed Test 0.5.3 allows remote attackers to read files outside the web root through crafted GET requests. The HTTP request handler accepts parent-directory segments in the URL path and resolves them without enforcing containment under the served directory. No authentication or user interaction is required, and exposure is limited to files readable by the server process.
