Users of WordPress may need to perform an urgent update related to the popular BackupBuddy plugin. BackupBuddy is a plugin which offers backup solutions designed to combat “hacks, malware, user error, deleted files, and running bad commands”. Unfortunately, running an older version of BackupBuddy could [leave your site open to potential breaches](). According to Security Week, the issue tagged as [CVE-2022-31474]() is down to an “insecure method of downloading the backups for local storing”. This results in people being able to grab files from the server without having been properly authenticated first.

## Traversing a WordPress installation

The vulnerability is listed as a “Directory Traversal Vulnerability”, and affects users running BackupBuddy from version 8.5.8.0 up to 8.7.4.1. The developers make the following observations:

* Using this vulnerability, attackers can view the contents of any file on your server which is readable by the WordPress installation. Sensitive files could be made available to the attackers, which is not something you’d want to happen.
* The vulnerability is being actively exploited in the wild. Sometimes you get lucky and find that something has been patched before anyone can make use of it. This isn’t the case here, sadly.
* The developers have made the security update available to anybody running BackupBuddy, regardless of version. No matter which licence you’re using, you can apply the fix. In theory, there is no need for anyone, anywhere to be running a vulnerable installation with the fix available to install.

## Next steps to take for BackupBuddy users

* Backup to version 8.7.5 right away. You should be doing this whether or not you’re concerned by the above security issue. Old versions of products frequently fall victim to additional security issues over time, especially if they’re no longer maintained.
* Reset your database password if you suspect there’s been a compromise of your WordPress installation.
* Change your WordPress salts. These are tools at your disposal used to [help keep passwords for your site secure]().
* Reset and update anything else not for public consumption in your wp-config.php, for example stored API keys for other services.

## The risks of not updating your site and plugins

WordPress is an immensely popular target for people fully invested in site compromise. Hijacked sites can be used for SEO poisoning, redirecting to malicious sites, spam, malware installation, phishing, and more.

If you’re running BackupBuddy, go and check your current version and update right away. Once that’s done, it would be wise to ensure everything else on your WordPress installation is fully up to date too. Let’s not make it easy for those up to no good: It won’t help your business, or the people who make use of your site.Read More
