"The remote host is running a version of FortiManager that is 5.0.x
prior to 5.0.11 or 5.2.x prior 5.2.2. It is, therefore, affected by
multiple vulnerabilities :

  - An unspecified flaw exists that allows an
    unauthenticated, remote attacker to inject arbitrary OS
    commands. (CVE-2015-3611)

  - A cross-site scripting (XSS) vulnerability exists due to
    improper validation of user-supplied input. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to follow a specially crafted link, to
    execute arbitrary script code in a user's browser
    session. (CVE-2015-3612)

  - An unspecified SQL injection vulnerability exists due to
    improper sanitization of user-supplied input before
    using it in SQL queries.

  - An unspecified local privilege escalation vulnerability
    exists in the command line interface.

  - A cross-site scripting vulnerability exists due to
    improper validation of user profile information.

  - An unspecified arbitrary file download vulnerability
    exists. An attacker can exploit this to disclose
    sensitive information.

  - An unspecified remote privilege escalation
    vulnerability exists. An attacker can exploit this by
    modifying specific parameters.");
