The remote host is running a version of Juniper ScreenOS prior to 5.4.0r10 / 6.0.0r6 / 6.1.0r2. It is, therefore, affected by a cross-site scripting vulnerability due to improperly sanitizing user input to the web interface and telnet login pages. An attacker could exploit this vulnerability by tricking a user into requesting a maliciously crafted URL, resulting in arbitrary script code execution.
