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

The CVE record's CNA (Brocade Communications Systems LLC, a Broadcom Company) lists Brocade Fabric OS versions before 9.2.2d and 10.0.0 up to and including 10.0.0a1 as affected. No release containing a fix is confirmed on record.

An OS command injection vulnerability exists in the configuration management subsystem of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When performing a configuration download operation, the management daemon will relay configuration parameters, user-supplied relay host strings, and filenames directly to an internal utility script without sufficient character set validation. Because the local utility fails to sanitize shell metacharacters before processing them in a system shell command, a malicious or compromised configuration file can cause arbitrary operating system commands to be executed on a remote local switch when an administrator initiates a configuration download.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Data Freshness Timeline

(refreshed 30× in last 7d / 30× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures).
