High-Tech Bridge SA Security Research Lab has discovered vulnerability in Serendipity which could be exploited to perform cross-site request forgery attacks.
The vulnerability exists due to insufficient validation of the request origin in serendipity_admin.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and execute arbitrary HTML and script code in user`s browser in context of the vulnerable site. Successful exploitation requires that victim uses "Remember me" feature in the Serendipity backend to login.
<form action="http://host/serendipity_admin.php?" method="post" name="main" >

|Upgrade to version 1.5.4.|
