Impact

An attacker may be able to derive the TLS session key and fully decrypt
the TLS traffic to access any sensitive information that is transmitted,
such as login credentials and credit card numbers.



Recommendations

System administrators will need to patch their systems if their TLS are
implemented using RSA ciphers by the affected vendors/implementations.
Visit https://robotattack.org for more information on the respective
vendor's patches.

If patches are not available, consider disabling TLS RSA cipher suites,

if

possible, with the help of the product's documentation or seek

assistance

from the vendor.



Disabling RSA ciphers on a V7R1 system will basically break SSL, since
V7R1 only supports RSA ciphers.

Would need to upgrade to V7R2 or V7R3 for the newer ciphers.



For those running SSL on V7R1, is this the end?

Hi Rob:



We updated the cipher specs (via the notes.ini) and now pass the test

for

Bleichenbacher's Oracle Threat (ROBOT) for both traveler and domino



SSLCipherSpec=C030009FC02F009EC028006BC0270067





This fixes domino but now we have to handle the IBMi apache servers as
well.
