CVE-2024-52309: SFTPGo is a full-featured and highly configurable SFTP, HTTP/S, FTP/S and WebDAV server

SFTPGo is a full-featured and highly configurable SFTP, HTTP/S, FTP/S and WebDAV server - S3, Google Cloud Storage, Azure Blob.

SFTPGo is a full-featured and highly configurable SFTP, HTTP/S, FTP/S and WebDAV server - S3, Google Cloud Storage, Azure Blob. One powerful feature of SFTPGo is the ability to have the EventManager execute scripts or run applications in response to certain events. This feature is very common in all software similar to SFTPGo and is generally unrestricted. However, any SFTPGo administrator with permission to run a script has access to the underlying OS/container with the same permissions as the user running SFTPGo. This is unexpected for some SFTPGo administrators who think that there is a clear distinction between accessing the system shell and accessing the SFTPGo WebAdmin UI. To avoid this confusion, running system commands is disabled by default in 2.6.3, and an allow list has been added so that system administrators configuring SFTPGo must explicitly define which commands are allowed to be configured from the WebAdmin UI.

What it means for a small business

If your business uses sftpgo, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.63%, higher than 50% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 29, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
