According to its banner, the version of lighttpd running on the remote host is prior to 1.4.16. It is, therefore, affected by multiple vulnerabilities :
mod_auth allows remote attackers to cause a denial of service via unspecified vectors involving (1) a memory leak, (2) use of md5-sess without a cnonce, (3) base64 encoded strings, and (4) trailing whitespace in the Auth-Digest header.
(CVE-2007-3946)
The server allows remote attackers to cause a denial of service by sending an HTTP request with duplicate headers.
(CVE-2007-3947)
The server might accept more connections than the configured maximum, which allows remote attackers to cause a denial of service via a large number of connection attempts.
(CVE-2007-3948)
mod_access ignores trailing / (slash) characters in the URL, which allows remote attackers to bypass url.access-deny settings (CVE-2007-3949)
The server, when run on 32 bit platforms, allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors involving the use of incompatible format specifiers in certain debugging messages in the (1) mod_scgi, (2) mod_fastcgi, and (3) mod_webdav modules. (CVE-2007-3950)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
