Detailsinfo

A vulnerability was found in drakkan sftpgo up to 2.6.2 and classified as problematic. This issue affects an unknown part of the component EventManager. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2024-52309 since 11/06/2024. The exploitation is known to be easy. The attack may be initiated remotely. The exploitation needs additional levels of successful authentication. Neither technical details nor an exploit are publicly available.
