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 41th 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 AC-6 (Least Privilege) — 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-2025-58383 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 (NIST 800-53 r5) AI

Least privilege directly requires that only the minimum necessary authorizations are granted, structurally eliminating execution with unnecessary privileges.

PR.AA-05 mostly match
prevents

PR.AA-05 directly enforces least privilege so largely eliminates CWE-250 at design time, yet the weakness can still arise from runtime escalation paths, third-party code, or misapplied role definitions outside this single control.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Requiring explicit justification and time-limited grants discourages the routine allocation of unnecessary privileges that would otherwise allow execution with more rights than required.

prevents

Restricting privileged utilities to the fewest trusted users and requiring explicit authorization directly stops developers or operators from embedding or invoking code that runs with unnecessary elevated rights.

prevents

Mandating separate non-privileged identities for routine work and restricting privileged accounts to administrative tasks reduces the chance that everyday operations run with unnecessary elevated rights.

prevents

The control explicitly calls for minimizing privileged identities and disabling unnecessary accounts, thereby reducing the number of processes that run with unnecessary privileges.

prevents

The requirement to restrict privileged access and apply segregation of duties limits the number of processes or accounts that must run with elevated rights, lowering the impact of unnecessary privilege assignments.

mitigates

Forcing distinct roles for initiating versus executing changes reduces the chance that an individual will run with unnecessary privileges to perform both steps.
