DCForum cgforum.cgi CGI script allows remote attackers to read arbitrary files, and delete the program itself, via a malformed "forum" variable.

dcboard.cgi in DCForum 2000 1.0 allows remote attackers to execute arbitrary commands by uploading a Perl program to the server and using a .. (dot dot) in the AZ parameter to reference the program.
