Lifecycle Timeline
3DescriptionCVE.org
A privilege escalation vulnerability exists in the internal Command-Line Interface (CLI) authorization handling mechanism of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user or local process that can manipulate the process execution environment can bypass Role-Based Access Control (RBAC) validation checks. Successful exploitation allows an attacker to elevate privileges to root
AnalysisAI
Privilege escalation in Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1 allows an authenticated CLI user or local process to bypass Role-Based Access Control (RBAC) validation by manipulating the process execution environment, resulting in root privileges. The flaw requires local access (AV:L), a low-privilege authenticated foothold (PR:L), and high attack complexity (AC:H) to control environment variables or settings, sharply narrowing exposure. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already be an authenticated CLI user OR a local process on the Brocade Fabric OS switch, AND to be able to manipulate the process execution environment (e.g., environment variables/settings that feed the internal CLI authorization logic) so that RBAC validation is bypassed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but second-tier priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Brocade Fabric OS 9.2.2d or later for the 9.x branch, and to a version beyond 10.0.0a1 for the 10.x branch as directed by the vendor advisory at https://support.broadcom.com/external/content/SecurityAdvisories/0/39154. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Brocade Fabric OS deployments and identify every switch running a version earlier than 9.2.2d or within the 10.0.0 through 10.0.0a1 range, restrict CLI and console access to a minimal set of trusted administrators, and rotate credentials for any shared or local accounts. …
