Detailsinfo

A vulnerability was found in drakkan sftpgo up to 2.6.4. It has been classified as critical. This affects some unknown processing. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

SFTPGo is an open source, event-driven file transfer solution. SFTPGo supports execution of a defined set of commands via SSH. Besides a set of default commands some optional commands can be activated, one of them being `rsync`. It is disabled in the default configuration and it is limited to the local filesystem, it does not work with cloud/remote storage backends. Due to missing sanitization of the client provided `rsync` command, an authenticated remote user can use some options of the rsync command to read or write files with the permissions of the SFTPGo server process. This issue was fixed in version v2.6.5 by checking the client provided arguments. Users are advised to upgrade. There are no known workarounds for this vulnerability.
