Threat & Defense at a Glance
Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Policy promotes least privilege by defining necessary privileges and management commitment to them.
Supervision detects and allows removal of unnecessary privileges that enable execution with excess rights.
Reviewing accounts for compliance, disabling/removing unneeded accounts, and aligning with termination processes prevents execution with unnecessary privileges.
Separation of duties prevents any single user from holding all privileges needed to complete a critical task, directly reducing execution with unnecessary privileges.
Directly prevents execution with more privileges than needed for assigned tasks.
Role-based training on least privilege principles reduces the chance personnel assign or retain unnecessary privileges.
Analysis of audit records can identify execution with unnecessary privileges through unusual activity patterns.
Automatic termination after a defined period eliminates unnecessary privileges from persistent connections.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Direct privilege escalation via exploitation of unnecessary privileges (CWE-250) allowing bypass of controls for arbitrary command execution by an authenticated admin user.
NVD Description
A vulnerability in Brocade Fabric OS versions before 9.2.1c2 could allow an administrator-level user to execute the bind command, to escalate privileges and bypass security controls allowing the execution of arbitrary commands.
Deeper analysisAI
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.
