Descriptions
The path normalization mechanism in PathResource class in Eclipse Jetty 9.3.x before 9.3.9 on Windows allows remote attackers to bypass protected resource restrictions and other security constraints via a URL with certain escaped characters, related to backslashes.
El mecanismo de normalización de ruta en la clase PathResource en Eclipse Jetty 9.3.x en versiones anteriores a 9.3.9 en Windows permite a los atacantes remotos evitar las restricciones de recursos protegidos y otras restricciones de seguridad a través de una URL con ciertos caracteres de escape relacionados con las barras invertidas.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Eclipse Jetty. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the way the ContextHandler class restricts access to protected resources. By issuing a crafted request, an attacker can gain access to the code of a web application deployed in Jetty. An attacker can use this knowledge in further attacks against the web application. Additionally, if the web application allows file uploads, it may be possible for an attacker to modify the code of the web application, achieving a direct path to executing arbitrary code under the context of the server process.
