Medium Nessus Network Monitor Plugin ID 4114
SynopsisThe remote host is vulnerable to a script injection attack.
DescriptionThe version of WordPress installed on the remote host is vulnerable to a file upload attack. An attacker exploiting this flaw would only need to be able to send custom queries to the 'wp-app.php' or 'app.php' script. Successful exploitation would result in the attacker uploading arbitrary code that could then be executed with the privileges of the web server.
SolutionUpgrade to WordPress 2.2.1, or later.
