Jenkins <=2.196 - Cookie Exposure

id: CVE-2019-10405

info:
  name: Jenkins <=2.196 - Cookie Exposure
  author: c-sh0
  severity: medium
  description: Jenkins through 2.196, LTS 2.176.3 and earlier prints the value of the cookie on the /whoAmI/ URL despite it being marked HttpOnly, thus making it possible to steal cookie-based authentication credentials if the URL is exposed or accessed via another cross-site scripting issue.
  impact: |
    The exposure of cookies can lead to session hijacking, unauthorized access, and potential data breaches.
  remediation: |
    Upgrade Jenkins to a version higher than 2.196 to mitigate the vulnerability.
