CNA source text (English)
The function that is used to parse the Authentication header in Brocade Fabric OS Web application service before Brocade Fabric OS v9.0.1a and v8.2.3a fails to properly process a malformed authentication header from the client, resulting in reading memory addresses outside the intended range. An unauthenticated attacker could discover a request, which could bypass the authentication process.
