This vulnerability only impacts sites running BackupBuddy versions 8.5.8.0 through 8.7.4.1.

There are indications that this vulnerability is still being actively exploited. However, ithemes readily patched the vulnerability and has requested its users to ensure they are using the 8.7.5 or higher version of the BackBuddy plugin.

What Should I Do?

Update immediately to the latest 8.7.5 patched version.

The breach allowed malicious users to view the contents of any file on a server that a WordPress installation can read.

Examples are the WordPress wp-config.php file and, depending on the server setup, other sensitive files like /etc/passwd. Therefore, it is imperative to upgrade immediately to the latest safe version.

How to Tell if I Am Affected

You can diagnose if your site has been compromised by finding any text containing local-destination-id and wp-config.php with an HTTP 2xx Response in your server logs.

The security breach was identified on BackBuddy versions 8.5.8.0 to 8.7.4.1.
