Executive Summary

CVE-2024-42450 exposes Versa Director’s PostgreSQL database due to a default common password and listening on all interfaces, enabling unauthenticated attackers to read the database, access local filesystem, and potentially elevate privileges. No production exploitation reported; a lab proof‑of‑concept exists. Mitigation: version 22.1.4 automatically restricts Postgres and HA ports to local/peer directors; older releases require manual hardening of HA ports (see Versa docs). The vulnerability is mitigated by published firewall guidelines and is not exploitable on Versa‑hosted head ends.

Authoritative CVE Metadata - CVSS Base Score: 10.0 (CRITICAL) - Published: 2024-11-19T18:15:20.560 - Last Modified: 2026-09-03T18:22:14.940

Original Description: The Versa Director uses PostgreSQL (Postgres) to store operational and configuration data. It is also needed for High Availability function of the Versa Director. The default configuration has a common password across all instances of Versa Director. By default, Versa Director configures Postgres to listen on all network interfaces. This combination allows an unauthenticated attacker to access and administer the database or read local filesystem contents to escalate privileges on the system.

Exploitation Status: Versa Networks is not aware of this exploitation in any production systems. A proof of concept exists in the lab environment.

Workarounds or Mitigation: Starting with the latest 22.1.4 version of Versa Director, the software will automatically restrict access to the Postgres and HA ports to only the local and peer Versa Directors. For older releases, Versa recommends performing manual hardening of HA ports. Please refer to the following link for the steps https://docs.versa-networks.com/Solutions/System_Hardening/Perform_Manual_Hardening_for_Versa_Director#Secure_HA_Ports

This vulnerability is not exploitable on Versa Directors if published Firewall guidelines are implemented. We have validated that no Versa-hosted head ends have been affected by this vulnerability. All Versa-hosted head ends are patched and hardened.
