AI Analysis

Impact

The vulnerability permits an authenticated low‑privilege operator to modify the state of specific settings through the HPE Networking Fabric Composer API, effectively elevating their privileges and enabling unauthorized configuration changes. This access control flaw can compromise the integrity and availability of the network environment by allowing altered system states that may lead to misconfiguration, service degradation, or interruption.

Affected Systems

HPE Networking Fabric Composer, a product from Hewlett Packard Enterprise. Version information is not disclosed in the advisory.

Risk and Exploitability

The CVSS score of 6.5 indicates moderate severity, and the EPSS score of '< 1%' reflects a very low probability of exploitation. It is not listed in the CISA KEV catalog. The vulnerability requires the attacker to be authenticated to the API; successful authentication is the prerequisite before the broken access control can be abused. No widespread exploitation has been reported at this time.

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the most recent HPE Networking Fabric Composer patch or firmware update that resolves the access control issue.
  • Enforce strict least‑privilege policies by removing or reducing the operator role’s ability to invoke configuration API endpoints.
