Note regarding US-Cert advisory 120541 In order to address the SSL and TLS vulnerability issue discussed in US-Cert advisory 120541, the Web server re-negotiation feature has been disabled in this release so that SSL re-negotiation requests will not be honored by the Brocade IP device Web server. Based on Cert advisory 120541, the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols are vulnerable to Man-In-The-Middle (MITM) attacks. Vulnerability is in the way SSL and TLS protocols allow re-negotiation requests, which may allow a MITM to inject arbitrary requests into an application HTTP protocol stream. This could result in a situation where the MITM may be able to harm the Brocade IP device through the Web Management interface.

Note regarding US-Cert advisory 120541
In order to address the SSL and TLS vulnerability issue discussed in US-Cert advisory 120541, the Web
server re-negotiation feature has been disabled in this release so that SSL re-negotiation requests
will
not
be honored by the Brocade IP device Web server.
Based on Cert advisory 120541, the Secure Sockets Layer (SSL) and Transport Layer Security (TLS)
protocols are vulnerable to Man-In-The-Middle (MITM) attacks.
Vulnerability is in the way SSL and TLS
protocols allow re-negotiation requests, which may allow a MITM to inject arbitrary requests into an
application HTTP protocol stream.
This could result in a situation where the MITM may be able to harm
the Brocade IP device through the Web Management interface.
