Accepted Answer

What exactly is the vulnerability in UpdraftPlus?

The vulnerability is a cross-site request forgery (CSRF) issue affecting UpdraftPlus versions up to and including 1.23.10. Due to insufficient validation, an attacker can modify the configured Google Drive backup location by tricking an admin into clicking a malicious link. This could let the attacker gain access to sensitive WordPress backups.

Question 2

How can this vulnerability be exploited?

The vulnerability can be exploited without authentication. An attacker just needs to trick an admin into clicking a link, visiting a compromised site, opening an email, etc. This would send a forged request that changes the Google Drive backup location to one the attacker controls. They could then access any new backups.

Question 3

What information is at risk from this vulnerability?

Accepted Answer

What information is at risk from this vulnerability?

Exploitation of this vulnerability can expose WordPress backups stored on Google Drive. These may contain sensitive data like database credentials, user details, unpublished content, and more. This presents risks of data breach, account takeover, blackmail, and other issues.

Question 4

I use UpdraftPlus. What should I do?

Accepted Answer

I use UpdraftPlus. What should I do?
