DESCRIPTION:
Multiple vulnerabilities have been discovered in Enable Media
Replace plugin for WordPress, which can be exploited by malicious
users to conduct SQL injection attacks and compromise a vulnerable
system.

1) Input passed via the "attachment_id" parameter to
wp-admin/upload.php (when "page" is set to
"enable-media-replace/enable-media-replace.php" and "action" is set
to "media_replace") is not properly sanitised before being used in
SQL queries. This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code.

2) The wp-content/plugins/enable-media-replace/upload.php script
allows replacing existing files (when the "replace_type" POST
parameter is not set to "replace"). This can be exploited to execute
arbitrary code by uploading a PHP file.

Successful exploitation of these vulnerabilities requires "Author"
role.

The vulnerabilities are confirmed in version 2.3. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
Grant the "Author" role to trusted users only.
