Ruckus Unleashed: Improper Limitation of a Pathname to a Restricted Directory
CVE-2025-46120 is a critical-severity improper limitation of a pathname to a restricted directory vulnerability in Ruckus Unleashed from Ruckuswireless, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 200.15.6.212.14, 200.17.7.0.139 as the first without the flaw, so updating Ruckus Unleashed to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.05% chance of exploitation within 30 days, higher than 65% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Ruckus Unleashed to 200.15.6.212.14 or 200.17.7.0.139, whichever matches your release line, or a later version.
- Update Ruckus Zonedirector to 10.5.1.0.279 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
An issue was discovered in CommScope Ruckus Unleashed prior to 200.15.6.212.27 and 200.18.7.1.323, and in Ruckus ZoneDirector prior to 10.5.1.0.282, where a path-traversal flaw in the web interface lets the server execute attacker-supplied EJS templates outside permitted directories, allowing a remote unauthenticated attacker who can upload a template (e.g., via FTP) to escalate privileges and run arbitrary template code on the controller.

The underlying weakness: Improper Limitation of a Pathname to a Restricted Directory
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.
How developers prevent this class of flaw
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
