Security Bulletin: Potential security exposure with IBM WebSphere DataPower SOA
Appliance (CVE-2013-0169 also known as "Lucky 13")
WebSphere DataPower SOA Appliances
3.8.2, 4.0.1, 4.0.2, 5.0.0
Security fix for SSL/TLS vulnerability CVE-2013-0169 (also known as "Lucky 13")
A recently discovered SSL, TLS and DTLS Plaintext Recovery Attack, known as
"Lucky 13" (CVE-2013-0169) will be addressed in the WebSphere DataPower SOA
appliance by APAR fix IC90431.
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.
