The remote host is affected by the vulnerability described in GLSA-200804-08 (lighttpd: Multiple vulnerabilities)
Julien Cayzax discovered that an insecure default setting exists in mod_userdir in lighttpd. When userdir.path is not set the default value used is $HOME. It should be noted that the 'nobody' user's $HOME is '/' (CVE-2008-1270). An error also exists in the SSL connection code which can be triggered when a user prematurely terminates his connection (CVE-2008-1531).
Impact :
A remote attacker could exploit the first vulnerability to read arbitrary files. The second vulnerability can be exploited by a remote attacker to cause a Denial of Service by terminating a victim's SSL connection.
Workaround :
As a workaround for CVE-2008-1270 you can set userdir.path to a sensible value, e.g. 'public_html'.
