The remote web server can be manipulated to disclose source code.
The remote host is running Lighttpd, a small web server. This version of Lighttpd is vulnerable to an information disclosure flaw. The 'mod_cgi' module, when put under a considerable load, could fail to fork its process. Such a failure would lead to the web server returning the source code of the CGI script that had been requested. An attacker exploiting this flaw would be able to gain access to potentially confidential data.
Upgrade to version 1.4.19 or higher.
