CVE-2016-9646 [MEDIUM] CVE-2016-9646 ikiwiki: Commit metadata forgery
CVE-2016-9646 ikiwiki: Commit metadata forgery
CGI::FormBuilder->field has a context-dependent API, similar to the CGI->param API that led to Bugzilla's CVE-2014-1572. Parts of ikiwiki incorrectly called this method in list context when a scalar result, which could lead to two relatively minor attacks:
In the comments plugin, an attacker who was able to post a comment could give it a user-specified author and author-URL even if the wiki configuration did not allow for that, by crafting multiple values to other fields. Also, in the editpage plugin, an attacker who was able to edit a page could potentially forge commit authorship by crafting multiple values for the rcsinfo field.
