Jennifer Bornholt has discovered a vulnerability in the JoomShopping
component for Joomla!, which can be exploited by malicious users to
conduct script insertion attacks.
Input passed via the "user_name" POST parameter to index.php (when
"option" is set to "com_jshopping", "controller" is set to "product",
"task" is set to "reviewsave", and "Itemid" is set to a valid item
identifier) is not properly sanitised before being used. This can be
exploited to insert arbitrary HTML and script code, which will be
executed in a user's browser session in context of an affected site
when the malicious data is being viewed.
The vulnerability is confirmed in version 4.3.0. Prior versions may
also be affected.
Update to version 4.3.1 or later.
