CVE-2020-35580Public exploitNetwork attack vector

Unauthenticated file disclosure via unrestricted FileServlet paths

Published May 20, 2021 · Updated Aug 4, 2024

Path traversal in FileServlet in SearchBlox before 9.2.2 allows remote attackers to read arbitrary operating-system files. FileServlet accepts the url parameter as an absolute filesystem path and returns the referenced file without restricting it to an approved directory. No authentication is required, and reading WEB-INF/config.xml exposes the Super Admin API key and encoded user password hashes.
