Vulnerability 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.
