Severity

high7.6

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

The Node.js web service on Versa VOS versions 21.1.1 to 21.2.3, 22.1.2 to July 2, 2026, and 23.1.2 to Aug 3, 2026, uses default credentials and HTTP Basic Authentication, allowing an attacker with network access to authenticate and perform provisioning actions. The service is not required after provisioning and can be disabled.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Attack conditions

No attack-condition excerpt has been identified here. Review the full source description and references for authentication, network access, and configuration requirements.

Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

The mitigation is to disable the Nodejs web service on the VOS. Instructions to disable the Nodejs web service are available on the Versa documentation page at the below link:

Original source description

Read the full publisher 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.
