CVE-2025-58382 is a high-severity Authentication Bypass by Primary Weakness (CWE-305) vulnerability in Broadcom Fabric Operating System. Its CVSS base score is 8.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 46th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to IA-2 (Identification and Authentication (Organizational Users)) and IA-8 (Identification and Authentication (Non-organizational Users)) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-58382 is a vulnerability in the secure configuration of authentication and management services within Brocade Fabric OS versions prior to 9.2.1c2. It stems from improper handling that enables an authenticated, remote attacker possessing administrative credentials to execute arbitrary commands with root privileges. The issue is classified under CWE-305 (Incorrect Inheritance of Permissions) and carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), indicating high confidentiality, integrity, and availability impacts.
An attacker requires valid administrative credentials and remote network access to the affected Fabric OS management interface to exploit this flaw. By leveraging specific commands such as "supportsave", "seccertmgmt", or "configupload", the attacker can escalate privileges and run arbitrary code as root, potentially leading to full system compromise, data exfiltration, or persistent access within the storage fabric environment.
Broadcom has published a security advisory addressing this vulnerability, available at https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/36849, which details the issue and recommends upgrading to Fabric OS 9.2.1c2 or later to mitigate the risk.
