Description
Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1 directly accepts Apache configuration file data during service setup or re-initialization. An attacker capable of corrupting the configuration structure will prevent the web management service from starting or recovering during service bring-up, leading to a persistent Denial of Service (DoS) of the administrative web interface.

AI Analysis

Impact

Brocade Fabric OS accepts raw Apache configuration data during service setup or reinitialization. If an attacker corrupts that configuration structure, the web management service fails to start or cannot recover during a bring‑up cycle, resulting in a persistent loss of access to the administrative web interface. This weakness is a CWE‑93 vulnerability.

Affected Systems

Fabric OS versions earlier than 9.2.2d and all 10.0.0 releases up to 10.0.0a1 are vulnerable. Later 9.2.2d and 10.0.1 builds contain the fix and are not affected.

Risk and Exploitability

The CVSS score is 6.8, indicating moderate severity, and the vulnerability is not listed in the CISA KEV catalog. The attack vector is inferred to require the attacker to have write access to the configuration files used during service setup, which allows the attacker to trigger a denial of state of the management service. The EPSS score is not available, so the likelihood of exploitation is uncertain but the denial can be sustained indefinitely.

Remediation

Vendor Solution

Security update is provided in Brocade Fabric OS 9.2.2d and 10.0.1


OpenCVE Recommended Actions

  • Apply the Brocade Fabric OS security update 9.2.2d or 10.0.1.
  • Restrict write access to the Apache configuration files used by Fabric OS to authorized personnel only.
  • If a patch cannot be applied immediately, temporarily disable the web management service to prevent ongoing denial of service.
  • Monitor system logs for failed service starts or abnormal configuration changes.
