CVE-2026-107241 (GCVE-0-2026-107241)

Vulnerability from cvelistv5 – Published: 2026-11-10 00:32 – Updated: 2026-11-10 00:32
VLAI
Summary
The Node.js web service on VOS (previously Versa FlexVNF) is used for URL-based Zero Touch Provisioning (ZTP) of the VOS appliance and is not required after provisioning is complete. This service authenticates users and administrators to its web interface during initial provisioning using default credentials and HTTP Basic Authentication. An attacker with network access who knows the default credentials could authenticate to the service and perform provisioning actions on the VOS appliance.  Versa’s security hardening guide for Hubs, Branches, and Controllers recommends disabling the Node.js web service after the initial provisioning of the VOS device. This vulnerability is not exploitable on VOS devices where the Node.js web service has been disabled.
