Junos device is affected by multiple vulnerabilities in the J-Web
component :

  - A cross-site scripting vulnerability exists due to a

    A remote attacker, using a crafted request, can exploit
    this to gain access to session credentials or execute
    administrative actions through the user's browser.

  - A denial of service vulnerability exists in error
    handling that allows an attacker to crash the J-Web
    service.
