'description' => %q{
this module exploits a vulnerability found in wikkawiki. when the spam logging
feature is enabled, it is possible to inject php code into the spam log file via the
useragent header , and then request it to execute our payload. there are at least
three different ways to trigger spam protection, this module does so by generating
10 fake urls in a comment (by default, the max_new_comment_urls parameter is 6).
please note that in order to use the injection, you must manually pick a page
first that allows you to add a comment, and then set it as 'page'.
