The default configuration of Cobalt Raq2 and Raq3 servers allows remote access to .htaccess files. This could lead to unauthorized retrieval of username and password information for restricted portions of a website hosted on the server. 

Make a regular GET request, specifying an .htaccess file ie:
http ://target/path/.htaccess
