CVE-2025-23173 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in Director from Versa, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Director versions: 21.2.2 and earlier; 21.2.3 and earlier; 22.1.1 and earlier, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.66% chance of exploitation within 30 days, higher than 52% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Director you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on security-portal.versa-networks.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
The Versa Director SD-WAN orchestration platform provides direct web-based access to uCPE virtual machines through the Director GUI. By default, the websockify service is exposed on port 6080 and accessible from the internet. This exposure introduces significant risk, as websockify has known weaknesses that can be exploited, potentially leading to remote code execution. Versa Networks is not aware of any reported instance where this vulnerability was exploited. Proof of concept for this vulnerability has been disclosed by third party security researchers. Workarounds or Mitigation: Restrict access to TCP port 6080 if uCPE console access is not necessary. Versa recommends that Director be upgraded to one of the remediated software versions.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How developers prevent this class of flaw
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
