Lifecycle Timeline
2DescriptionCVE.org
An input validation and output encoding vulnerability exists in the web management interface of Brocade Fabric OS versions before 10.0.1. When configuring Federated Authentication (FA), the system fails to sanitize the Identity Provider (IdP) issuer parameter. An authenticated administrator-or an attacker capable of supplying crafted FA configuration files during an import routine-can inject arbitrary web server directives. This can lead to service denial by preventing the web management daemon from starting, or potentially alter web server security controls.
AnalysisAI
Improper neutralization of CRLF sequences in the Federated Authentication (FA) configuration of Brocade Fabric OS before 10.0.1 lets an authenticated administrator - or anyone able to supply a crafted FA configuration file that an operator imports - inject arbitrary web server directives through the Identity Provider (IdP) issuer parameter, which can prevent the web management daemon from starting (denial of service) or alter web server security controls. Exploitation is heavily constrained: the target must run a vulnerable Fabric OS release with FA actually in use, the attacker needs administrative privilege (CVSS PR:H) and adjacent-network access to the management interface (AV:A), with no user interaction otherwise required, and no public exploit code has been identified at time of analysis. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that Federated Authentication (FA) be in use and that the attacker can set or import the IdP issuer parameter during FA configuration - either as an authenticated administrator (PR:H) with adjacent-network access to the web management interface, or by supplying a crafted FA configuration file that an operator imports. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a medium-severity, operator-dependent flaw rather than a top-priority 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 | The primary fix is to upgrade Brocade Fabric OS to 10.0.1 or later - the version line in which the affected pre-10.0.1 code is not present - following the Broadcom advisory at https://support.broadcom.com/external/content/SecurityAdvisories/0/39138 for exact upgrade guidance and any platform-specific notes. … Detailed patch versions, workarounds, and compensating controls in full report. |
