EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 85% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Insecure access controls on internal service ports in Brocade SANnav versions before 3.0.1a allow local, non-administrative host users to communicate directly with backend management services. A local attacker can leverage this exposed access to transmit commands to connected Fabric OS switches under the security context of the SANnav management user.
