Description

A flaw was found in Eclipse Jetty. An attacker could craft a specially formed HTTP Uniform Resource Identifier (URI) that, when processed by Jetty, results in an unresolved path. While Jetty itself is not directly affected, web applications relying on Jetty to provide resolved paths may be confused, potentially leading to unintended information disclosure. This could allow an attacker to access sensitive files or directories that should otherwise be protected.

Statement

Moderate impact: This path confusion vulnerability in Eclipse Jetty affects web applications that rely on Jetty to provide resolved paths. While Jetty itself correctly handles these paths and prevents direct file serving, vulnerable web applications may misinterpret unresolved paths, potentially leading to information disclosure.
