Overview

This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

SFTPGo is an open source, event-driven file transfer solution. SFTPGo versions before v2.7.1 contain an input validation issue in the handling of dynamic group paths, for example, home directories or key prefixes. When a group is configured with a dynamic home directory or key prefix using placeholders like %username%, the value replacing the placeholder is not strictly sanitized against relative path components. Consequently, if a user is created with a specially crafted username the resulting path may resolve to a parent directory instead of the intended sub-directory. This issue is fixed in version v2.7.1

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
