Summary

CVE-2025-9711 is a high-severity Least Privilege Violation (CWE-272) vulnerability in Broadcom Fabric Operating System. Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 3th 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-2025-9711 is a privilege escalation vulnerability in Brocade Fabric OS versions prior to 9.2.1c3. It enables a local authenticated user to elevate their privileges to root by exploiting the export option in the seccertmgmt and seccryptocfg commands. The issue is rated with a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-272 (Least Privilege Violation).

The vulnerability can be exploited by any local user with authenticated access to the system, requiring low complexity and no user interaction. Successful exploitation grants full root privileges, allowing the attacker to achieve high impacts on confidentiality, integrity, and availability, such as arbitrary code execution, data modification, or system disruption.

Broadcom has published a security advisory detailing the issue, available at https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/36852, which recommends upgrading to Fabric OS 9.2.1c3 or later to mitigate the vulnerability.

Mitigating Controls (NIST 800-53 r5) AI

AC-6 directly requires employing least privilege so that elevated rights are granted only when needed and revoked immediately afterward.

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.

mitigates

Restricts and monitors privileged utility programs, directly addressing the need to drop elevated rights immediately after use.

mitigates

Privileged access rights explicitly require least-privilege assignment and timely revocation after elevated operations.

prevents

Secure coding practices can prevent least-privilege violations but do not constitute the control itself.

mitigates

Information access restriction supports least privilege but does not specifically mandate dropping rights after privileged operations.
