Ikiwiki has always guarded against this one way or another; the current solution should detect all types of loops involving preprocessor directives. + +## Online editing of existing css and images + +A bug in ikiwiki allowed the web-based editor to edit any file that was in +the wiki, not just files that are page sources. So an attacker (or a +genuinely helpful user, which is how the hole came to light) could edit +files like style.css. It is also theoretically possible that an attacker +could have used this hole to edit images or other files in the wiki, with +some difficulty, since all editing would happen in a textarea. + +This hole was discovered on 10 Feb 2007 and fixed the same day with the +release of ikiwiki 1.42. A fix was also backported to Debian etch, as +version 1.33.1. I recommend upgrading to one of these versions if your wiki +allows web editing. |
