Lifecycle Timeline
2DescriptionCVE.org
An authentication logic and privilege escalation vulnerability exists in the account management interface of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. Under specific conditions, an authenticated user can bypass authorization restrictions intended to prevent modifying another account's access privileges. Exploitation allows a lower-privileged user to assign administrative roles to a target account, leading to localized privilege escalation.
AnalysisAI
Privilege escalation in Brocade Fabric OS (versions before 9.2.2d and 10.0.0 through 10.0.0a1) allows an authenticated low-privileged user on the adjacent management network to bypass authorization controls in the account management interface and assign administrative roles to other accounts. Exploitation requires specific conditions and high attack complexity (AC:H), but successful attacks can yield high integrity and availability impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an existing authenticated account with low privileges (PR:L) on the Brocade Fabric OS account-management interface, and network reachability limited to the adjacent management network (AV:A) rather than remote internet access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a medium-severity, authenticated privilege-escalation flaw whose real-world risk is moderate and unlikely to be a top-tier emergency. … 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 | Vendor-released patch: Upgrade to Brocade Fabric OS 9.2.2d or later for the 9.x branch; for the 10.0.0 branch, apply the latest fixed release as specified in the vendor advisory (https://support.broadcom.com/external/content/SecurityAdvisories/0/39156). … Detailed patch versions, workarounds, and compensating controls in full report. |
