CVE-2019-25087Network attack vector

Unauthenticated file read via unchecked URI traversal

Published Dec 27, 2022 · Updated Nov 19, 2024

Path traversal in Ramsey Kant HTTP Server allows remote attackers to read files outside the document root through crafted request URIs. ResourceHost::getResource concatenates the configured baseDiskPath with the untrusted uri without first rejecting ../ sequences. Unauthenticated network access to the listening HTTP service is sufficient, and the consequence is limited to reading server-accessible files.
