Summary
CVE-2024-2240 is a high-severity Execution with Unnecessary Privileges (CWE-250) vulnerability in Broadcom Brocade Sannav. Its CVSS base score is 8.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 42th 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.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-2240 affects the Docker daemon in Brocade SANnav versions prior to 2.3.1b, where it runs without auditing enabled. This misconfiguration, mapped to CWE-250 (Execution with Unnecessary Privileges), exposes the system to potential abuse by allowing actions to go unlogged and undetected. The vulnerability has a CVSS v3.1 base score of 7.2 (High), with vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, indicating network accessibility, low attack complexity, and high impacts on confidentiality, integrity, and availability.
A remote authenticated attacker with high privileges (PR:H) can exploit this vulnerability to execute various attacks on the SANnav system. The lack of auditing in the Docker daemon enables attackers to perform unauthorized operations without generating logs, facilitating stealthy compromise of the storage area network management platform while evading detection.
Mitigation is addressed in the Broadcom security advisory at https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/25401, which recommends upgrading to SANnav 2.3.1b or later to enable proper auditing in the Docker daemon.

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
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.
A.5.15's policy, requirements, and rules for determining/minimizing access rights (incl. privileged access restrictions, need-to-know, least-privilege-like mapping, and role-based consistency) directly stop most unnecessary-privilege execution by design; bounded remainder is runtime elevation or misconfigured enforcement that still requires other controls (e.g. 8.2, 8.3) to act.
Requiring explicit justification and time-limited grants discourages the routine allocation of unnecessary privileges that would otherwise allow execution with more rights than required.
Independent scrutiny can identify processes or services still running with unnecessary privileges and drive their reduction before an attacker can abuse them.
