Until such time as the APAR fix is available in a fix pack, a stream cipher (RC4) may be used to protect against this vulnerability. The protocol problem that allows the attack only affects block ciphers such as 3DES and AES. RC4 is a stream cipher supported by SSL/TLS and its use avoids this attack entirely. To configure this in the DataPower WebGUI, enter the string RC4-SHA:RC4-MD5 into the Ciphers property in the Crypto Profile and Save. With this configuration setting, DataPower will only negotiate strong, non-export cipher suites involving RC4 - a stream cipher rather than a block cipher.
