Summary

CVE-2025-58383 is a high-severity Execution with Unnecessary Privileges (CWE-250) vulnerability in Broadcom Fabric Operating System. Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 39.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and AC-6 (Least Privilege).

Deeper analysis

CVE-2025-58383 is a privilege escalation vulnerability in Brocade Fabric OS versions before 9.2.1c2. It enables an administrator-level user to execute the bind command, bypassing security controls and allowing the execution of arbitrary commands. The issue has 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) and is classified under CWE-250 (Execution with Unnecessary Privileges).

An administrator-level user can exploit this vulnerability remotely over the network with low attack complexity and no user interaction. Exploitation grants escalated privileges, enabling arbitrary command execution with high impacts to confidentiality, integrity, and availability.

The Broadcom security advisory at https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/36878 provides details on mitigation, including upgrading to Brocade Fabric OS version 9.2.1c2 or later.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly counters CWE-250 by restricting the administrator account from executing the bind command that enables arbitrary command escalation.

prevent

Enforces the security controls that the vulnerability explicitly bypasses when an admin-level user runs the bind command.

prevent

Requires timely application of the vendor patch (Fabric OS 9.2.1c2+) that eliminates the privilege-escalation flaw.
