Quick assessment

Affected
Versa VOS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

VOS（原 Versa FlexVNF）上的 Node.js Web 服务用于 VOS 设备的基于 URL 的零接触部署（ZTP），在部署完成后该服务即不再需要。在初始部署阶段，该服务使用默认凭据和 HTTP 基本认证机制对用户和管理员访问其 Web 界面进行身份验证。拥有网络访问权限且知晓默认凭据的攻击者，可成功通过该服务的身份验证，并在 VOS 设备上执行部署操作。 Versa 针对 Hub、Branch 和 Controller 的安全加固指南建议，在 VOS 设备完成初始部署后禁用 Node.js Web

Vulnerability Description
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.
