"According to its banner, the version of lighttpd running on the remote
host is prior to 1.4.35. It is, therefore, affected by the following
vulnerabilities :

  - A SQL injection flaw exists in the 'mod_mysql_vhost'
    module where user input passed using the hostname is not
    properly sanitized. A remote attacker can exploit this
    to inject or manipulate SQL queries, resulting in the
    manipulation or disclosure of data. (CVE-2014-2323)

  - A traverse outside of restricted path flaw exists with
    the 'mod_evhost' and 'mod_simple_vhost' modules where
    user input passed using the hostname is not properly
    sanitized. A remote attacker can exploit this to gain
    access to potentially sensitive data. (CVE-2014-2324)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
