DESCRIPTION:
Multiple vulnerabilities have been discovered in the XCloner plugin
for WordPress, which can be exploited by malicious people to conduct
cross-site scripting attacks and disclose sensitive information.

1) Input passed via the "mosmsg" parameter to
wp-content/plugins/xcloner-backup-and-restore/admin.cloner.php is not
properly sanitised in
wp-content/plugins/xcloner-backup-and-restore/admin.cloner.html.php
before being returned to the user. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.

2) Input passed via the "option" parameter to
wp-content/plugins/xcloner-backup-and-restore/admin.cloner.php (when
"task" is set to "dologin") is not properly sanitised in
wp-content/plugins/xcloner-backup-and-restore/cloner.functions.php
before being returned to the user. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.

Successful exploitation of this vulnerability requires that
"register_globals" is enabled.

3) Input passed via the "config" parameter to
wp-content/plugins/xcloner-backup-and-restore/cloner.cron.php is not
properly verified before being used to include files. This can be
exploited to include arbitrary files from local resources via
directory traversal attacks.

The vulnerabilities are confirmed in version 2.2.1. Other versions
may also be affected.

SOLUTION:
Upgrade to version 3.0.1, which fixes vulnerabilities #1 and #2. Edit
the source code to ensure that input is properly verified.
