Unknown Unknown - Not Provided
Directory Traversal in Rapid7 Velociraptor Allows Unauthorized File Upload

Publication date: 2025-12-29

Last updated on: 2026-02-20

Assigner: Rapid7, Inc.

Description
Rapid7 Velociraptor versions before 0.75.6 contain a directory traversal issue on Linux servers that allows a rogue client to upload a file which is written outside the datastore directory. Velociraptor is normally only allowed to write in the datastore directory. The issue occurs due to insufficient sanitization of directory names which end with a ".", only encoding the final "." AS "%2E". Although files can be written to incorrect locations, the containing directory must end with "%2E". This limits the impact of this vulnerability, and prevents it from overwriting critical files.

CWE ID Description
CWE-22 The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a directory traversal issue in Rapid7 Velociraptor versions before 0.75.6 on Linux servers. It allows a rogue client to upload a file that is written outside the intended datastore directory due to insufficient sanitization of directory names ending with a dot ('.'). The final dot is encoded as '%2E', which enables writing files outside the allowed directory.


How can this vulnerability impact me? :

The vulnerability can allow an attacker to write files outside the designated datastore directory, potentially leading to unauthorized file placement. However, the impact is limited because the containing directory must end with '%2E', which prevents overwriting critical files. The vulnerability can cause integrity issues but does not affect confidentiality or availability.


How can this vulnerability be detected on my network or system? Can you suggest some commands?

Detection involves monitoring for unusual file uploads or files written outside the Velociraptor datastore directory on Linux servers running versions prior to 0.75.6. Since exploitation requires directory names ending with '%2E', scanning for files or directories with names ending in '%2E' outside the datastore directory may help identify attempts. Specific commands are not provided in the available resources. [1]


What immediate steps should I take to mitigate this vulnerability?

The immediate mitigation step is to upgrade Velociraptor on Linux servers to version 0.75.6 or later, which contains the fix for this directory traversal vulnerability. Windows servers are not affected and do not require action. [1]
