|
info:
|
|
name: Eclipse Jetty ConcatServlet - Information Disclosure
|
|
author: pikpikcu
|
|
severity: medium
|
|
description: |
|
|
Eclipse Jetty through 9.4.40, through 10.0.2, and through 11.0.2 is susceptible to information disclosure. Requests to the ConcatServlet with a doubly encoded path can access protected resources within the WEB-INF directory, thus enabling an attacker to potentially obtain sensitive information, modify data, and/or execute unauthorized administrative operations in the context of the affected site.
|
|
remediation: |
|
|
Upgrade to Eclipse Jetty version 9.4.40 or later to mitigate this vulnerability.
