According to its banner, the version of lighttpd running on the remote host is prior to 1.4.19. Therefore, it may be, affected by the following vulnerabilities :
lighttpd does not properly calculate the size of a file descriptor array, which allows remote attackers to cause a denial of service (crash) via a large number of connections, which triggers an out-of-bounds access.
lighttpd sends the source code of CGI scripts instead of a 500 error when a fork failure occurs, which might allow remote attackers to obtain sensitive information.
When userdir.path is not set, uses a default of $HOME, which might allow remote attackers to read arbitrary files.
Note that Nessus has not tested for these issues but has instead relied only on the applicationโs self-reported version number.
