Description

Limny contains a flaw that allows a remote cross site scripting (XSS) attack. This flaw exists because the application does not validate the 'q', 'theme', 'language', 'tags', 'category', 'name', 'pageslinksby', 'itemsseperator', 'datetimetype', 'pageslinksby', 'itemsseperator', 'datetimetype', 'email', 'content', 'text' and 'summary' parameters upon submission to the index.php script. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.

Technical

This vulnerability for the 'q', 'theme', 'language', 'tags', 'category', 'name', 'pageslinksby', 'itemsseperator', 'datetimetype', 'pageslinksby', 'itemsseperator', 'datetimetype' is only present when the magic_quotes_gpc PHP option is set to 'off'.

Successful exploitation via the 'tags' and 'category' parameters to index.php requires the 'q' parameter is set to "admin/modules/post/new" and the user has permission to create new posts.

Successful exploitation via the 'name' parameter to index.php requires 'q' is set to "admin/modules/form/elements" and the user has permission to edit form elements.

Successful exploitation via the 'pageslinksby', 'itemsseperator', and 'datetimetype' parameters to index.php requires 'q' is set to "admin/modules/page/options" and the user has permission to edit page options.

Successful exploitation via the 'numberofposts', 'numberofpages', 'showsummaryinfullview', 'postlinksby', 'itemsseperator', 'postsseperator', and 'datetimetype' parameters to index.php requires 'q' is set to "admin/modules/post/options" and the user has permission to edit post options.

Success exploitation via the 'content' parameter to index.php requires 'q' is set to "admin/modules/block/new" and the user has permission to create new blocks.

Successful exploitation via the 'name' parameter to index.php requires 'q' is set to "admin/modules/navigation" and the user has permission to create new navigation items.

Successful exploitation via the 'text' parameter to index.php requires 'q' is set to "admin/modules/page/new" and the user has permission to create new pages.

Successful exploitation via the 'summary' and 'text' parameters to index.php requires 'q' is set to "admin/modules/post/new" and the user has permission to create new posts.
