Directory Traversal Vulnerability in Rapid7 Velociraptor on Linux Servers

CVE-2025-14728

What is CVE-2025-14728?

Rapid7 Velociraptor, specifically versions prior to 0.75.6, is exposed to a directory traversal vulnerability on Linux servers. This flaw allows unauthorized clients to upload files outside the designated datastore directory due to inadequate sanitization of directory names that conclude with a '.'. The only encoding applied is turning the final '.' into '%2E', which could lead to unintended file placements. While attackers can place files in incorrect directories, it is noteworthy that these directories must conclude with '%2E', which limits potential damage and protects critical system files.
