Summary
Transport Layer Security (TLS) padding vulnerability via a POODLE (Padding
Oracle On Downgraded Legacy Encryption) like attack affects IBM
PureApplication System.
Vulnerability Details
CVEID: CVE-2014-8730
DESCRIPTION: IBM PureApplication Server bundles IBM HTTP Server, which could
allow a remote attacker to obtain sensitive information, caused by the failure
to check the contents of the padding bytes when using CBC cipher suites of
some TLS implementations. A remote user with the ability to conduct a
man-in-the-middle attack could exploit this vulnerability via a POODLE
(Padding Oracle On Downgraded Legacy Encryption) like attack to decrypt
sensitive information and calculate the plain text of secure connections.
